@ Main Unit Lock
This transceiver allows you to separate the Front
Panel from the Main Unit so you can mount the
Front Panel in the most convenient location for
operating. The Main Unit could be placed ina
vehicle trunk, for example, since there are few
buttons or controls on it. If you separate the two
sections in this way, you may want to lock the Main
Unit buttons and the Main Tuning control. These
can be locked via Menu B, Nos. 68 and 69
{page 14}. The default for both menus is OFF
(unlocked).
Menu B, No. 68 locks or unlocks the Main Tuning
control. Furthermore, No. 68 has 2 types of lock.
It can lock the Main Tuning control only if FM
mode is selected ("F3") or if any mode is selected
("All"). Menu B, No. 69 locks or unlocks [PROC],
[AIP], [NB], and [PF].
m@ Microphone Lock
The Microphone Lock function disables everything
on the microphone except [PTT] and, if equipped,
the DTMF keypad.
Slide the Lock switch on the rear of the
microphone to "LOCK" to activate Microphone
Lock.
* Slide the Lock switch to the opposite position
when you want to unlock the microphone
buttons and keys.
AUTOMATIC POWER OFF (APO)
Automatic Power Off is a background function that
monitors whether any buttons have been pressed or
controls have been changed. If 3 hours pass without
either of the preceding, this function turns OFF the
power. The purpose is to save power during
unattended operation. However, 1 minute before the
power turns OFF, "APO" starts blinking and a series
of warning tones sound. Pressing any button or
turning a control during this series of tones stops the
shutdown process and resets the timer.
The function is disabled while scanning or while
accessing either Menu A or B. Activate APO via
Menu B, No. 58. To restore power after APO
activates, press [POWER] twice.
Note: APO turns OFF the power if no key entry is made for 180
minutes even if Tone Alert is ON.
7 AUXILIARY FUNCTIONS
CHANNEL DISPLAY
When this function is switched ON, the transceiver
data in Memory Recall is displayed by channel
numbers without showing the associated frequencies.
Channel Display is selected via Menu B, No. 75. The
default is Frequency Display (ON).
M.CH ry no FM
TRANSVERTER FREQUENCY DISPLAY
A transverter is a device that converts a range of
frequencies applied to the input of the transverter to a
different range of frequencies. The transverter's
output can be applied to a transceiver's input, and
then the transceiver is used to operate on the new
frequency range.
The Display of this transceiver can be changed to
show frequencies in the 1200 or 2400 MHz band via
Menu B, No. 76. The default is OFF. The new
ranges of frequencies that can be tuned in bands of
1 MHz are 1240 to 1299 MHz or 2400 to 2449 MHz.
Note: Direct entry of frequency is not possible while using the
Transverter Frequency Display function.
PEAK METER HOLD
This function adds a 2.5 second delay after the S/RF
meter reaches its peak value before dropping back to
0. The purpose of this delay is to allow the operator a
better chance to read the peak value.
Peak Meter Hold is selected via Menu B, No. 54. The
default is ON.
