Section 13-3 13-3 Short cut text entry, keypad with ïðñò keys Text may also be entered using a combination of the keypad and ï ð ñ ò keys. While in a text input menu, for flashing “ FUNC ” legend then refer to the following table. Look for the required character in the table then PUSH the key shown to the horizontal-left followed by the ð ñ ò & Note: The CASE SHIFT key is used to access lower case letters. Example: To select the letter “ N ” until the flashing “ FUNC ” is displayed. , the desired “ N ” character will be displayed and the cursor will move one position to the right. The flashing “ FUNC ” legend will continue to flash, if it is not required further , the number “ 4 ” will be displayed, ï for it to be removed from the LCD. Example: To select the letter “ e ” until the flashing “ FUNC ” is displayed. , the number “ 5 ” will be displayed, to instruct the CPU that a lower , the desired “ e ” character will be displayed and the cursor will move one position to the right.

A ‘HIGH’ pitched beep indicates correct operation while a ‘LOW’ pitched beep indicates that an error or unexpected entry has taken place. The volume of the beep is independent of the main volume control and can be separately defined. It is recommended that the beep facility be enabled, especially in the early days while gaining familiarity of the receiver. Beep is setup in the CONFIG menu. To access the config menu . The first item in the config menu is “ BEEP ”, the default is beep on with a volume level of 09. Use the main dial or ï ð keys to vary beep level between the range of OFF and 01 to 09 with 09 being the loudest. The key may be used as a short cut to 05. to accept the data and return to a standard display. Alternatively to abort entry or ò to move to the next item on the config menu (LAMP). 14-2 CONFIG LAMP The AR8200 is equipped with high intensity green LEDs to illuminate the LCD and front panel keypad when operating in areas of low level lighting. While the AR8200 is switched on and connected to an external power source such as the charger or d.c. lead, the lamp will be PERMANENTLY ON and cannot be switched off. The lamp will go out when the AR8200 is switched off (when the batteries are being charged etc). 106 Section 14-2, 14-3 The lamp may be configured in three ways: AUTO This setting is relevant when operating from internal batteries only. The lamp will automatically illuminate when the front panel and side panel keys are used. The lamp will remain illuminated for a further five second after the last key push and will then switch off. This is a good compromise setting for best visibility and battery life. CONT This setting is relevant when operating from internal batteries only. The lamp will CONTinuously illuminate the front panel and side panel keys. The lamp will only extinguish when the AR8200 is switched off. Of course continuous operation of the lamp will drain the internal batteries more quickly. OFF This setting is relevant when operating from internal batteries only. The lamp remains permanently extinguished, this is useful to maintain maximum battery life when used in areas of high light levels. The LAMP is setup in the CONFIG menu. To access the config menu . ò to move the cursor to the “ LAMP ” selection point. Use the main dial or ï ð keys to toggle the lamp between AUTO (default), CONT and OFF. The key may be used as a short cut to AUTO. to accept the data and return to a standard display. Alternatively to abort entry or ò to move to the next item on the config menu (CONTRAST). 14-3 CONFIG CONTRAST The AR8200 is equipped with variable LCD contrast which is adjustable in 32 steps to provide best visibility under different viewing angles, extremes of ambient light & temperature (and between sets due to variation). The default setting for contrast is 14. The display generally becomes too dark to read around 20 and too feint around 02, the key may be used as a short cut to 14. The CONTRAST is setup in the CONFIG menu. To access the config menu . ò twice to move the cursor to the “ CONTRAST ” selection point. Use the main dial or ï ð keys to vary the contrast level to achieve best visibility. to accept the data and return to a standard display. Alternatively to abort entry or ò to move to the next item on the config menu (POWER-SAVE). 107 Section 14-4 14-4 CONFIG Power save The POWER SAVE facility may be used to help the receiver to operate for longer periods of time between battery recharging. Power save is default OFF to prevent confusion while the AR8200 is in a “dormant” cycle as the receiver is effectively asleep and only wakes up for short periods to check for activity before going to sleep and becoming dormant again. & Note: While in a dormant state (waiting to cycle), the AR8200 behaves sluggishly. When power save is ON, the AR8200 will automatically switch ‘off and on’ but the display will appear permanently on as only the AR8200 “receive” circuitry is switched off and on (switching the receiver off for short periods of time is what saves power!), the microprocessor is left on permanently but in a reduced operating condition. When activated, two parameters may be varied to affect the way the receiver behaves, these are “ DELAY ” and “ CYCLE ”. DELAY: This parameter determines how long the AR8200 will remain active before going to sleep and becoming dormant and is timed from when the squelch last closed or keypad was last used. The available range is 01 to 30 seconds plus OFF (default off). When OFF, the power save does not operate. The key may be used as a short cut to OFF. CYCLE: When the receiver becomes dormant (delay has expired), the cycle parameter determines how long the AR8200 will remain dormant before its ‘wake up’ period begins. If a transmission takes place while dormant it will be missed, if however a transmission occurs during the wake up period, the AR8200 will continue to monitor until the transmission ends and DELAY / CYCLE takes place again. The available range is 0.5 to 9.5 seconds (default 3.0 seconds). The key may be used as a short cut to 3.0 seconds. three times to move the cursor to the POWER SAVE “ DELAY ” selection point. Use the main dial or . ò ï ð keys to vary the delay value, the key may be used as a short cut to OFF. to move the cursor to the POWER SAVE “ CYCLE ” selection point. ò 108 The POWER SAVE parameters are setup in the CONFIG menu. To access the config menu Section 14-4, 14-5, 14-6 Use the main dial or ï ð keys to vary the cycle value, the key may be used as a short cut to 3.0 seconds. to accept the data and return to a standard display. Alternatively to abort entry or ò to move to the next item on the config menu (AUTO PWR-OFF). 14-5 CONFIG Auto power off An auto power off facility is available to switch the AR8200 off automatically after a programmable period of squelch inactivity, this prevents the batteries from becoming flat when monitoring a completely inactive frequency. Note: Be careful how you use auto power off as it might catch you out one day (if a short auto-power-off period has been set), auto power off setting is not cancelled with power off / on… if the AR8200 appears to switch itself off for no reason, check to make sure that you haven’t enabled auto power off (there is no associated LCD legend). five times to move the cursor to the “ AUTO PWR-OFF ” selection point. Use the main dial or . ò keys to vary the time between 0.5 hours to 9.5 hours in 0.5 hr increments, the ï ð key may be used as a short cut to OFF. When the AR8200 squelch closes, the CPU will wait the length of time programmed in auto-power-off before automatically switching the AR8200 off. If the squelch opens again before auto switch off time has elapsed, the radio will not power down and the counter will be reset (i.e. an open squelch defeats auto power off). to accept the data and return to a standard display. Alternatively to abort entry or ò to move to the next item on the config menu (REMOTE BPS). 14-6 CONFIG REMOTE BPS The REMOTE BPS menu is used to configure the RS232 computer control settings as it is important that they exactly match those of an associated computer connection or another AR8200 (connected via the option socket and optional leads). The REMOTE BPS parameters are setup in the CONFIG menu. To access the config menu . six times to move the cursor to the “ REMOTE BPS ” selection point. Use the main dial or keys to vary the RS232 baud rate between 4800bps, 9600bps and 19200bps. The key may be used as a short cut to the default of 9600bps. ï ð 109 & AUTO POWER OFF is setup in the CONFIG menu. To access the config menu ò [ Pobierz całość w formacie PDF ] |
