MISCELLANEOUS SETTINGS

DISABLING THE TX/BUSY INDICATOR

Further battery conservation may be accomplished by disabling the TX indicator while transmitting and disabling the BUSY indicator while receiving a signal. Use the following procedure:

1. Press the [F] key, then press the [0(SET)] key to enter the Set mode.

2. Rotate the DIAL knob to select Set Mode Item 8: BSY.LED if

you wish to disable the BUSY indicator or Set Mode Item 48: TX.LED if you wish to disable the TX indicator.

3. Press the [F] key momentarily to enable adjustment of this Set

Mode Item. 4. Rotate the DIAL knob to set this Set Mode Item to “LED.OFF

(thus disabling the BUSY or TX lamp).

5. When you have made your selection, press the PTT switch to

save the new setting and exit to normal operation. 6. If you wish to re-enable the TX/BUSY Indicator, just repeat the

above procedure, rotating the DIAL knob to select “LED. ON” in step 4 above.

AUTOMATIC POWER-OFF (APO) FEATURE

The APO feature helps conserve battery life by automatically turning the radio off after a user-defined period of time within which there has been no dial or key activity. The avail- able selections for the time before power-off are 0.5 to 12.0 hours in 0.5 hour multiple, as well as APO Off. The default condition for the APO is OFF, and here is the procedure for activating it:

1. Press the [F] key, then press the [0(SET)] key to enter the Set mode.

2. Rotate the DIAL knob to select Set Mode Item 1: APO. 3. Press the [F] key momentarily to enable adjustment of this Set

Mode Item. 4. Rotate the DIAL knob to select the desired time period after

which the radio will automatically shut down. 5. When you have made your selection, press the PTT switch to

save the new setting and exit to normal operation.

When the APO is activated, the “” icon will appear on the LCD. If there is no action by you within the time interval programmed, the microprocessor will shut down the radio automatically.

Rotate the VOL/PWR knob counter-clockwise to the “off” position, then clockwise out of the click-stop, to turn the radio on after an APO shutdown.
