Side Panel Buttons
( 1 ) MON RES ( Monitor/Reset ) Button
Pressing and holding this button more than 2 seconds
(but less than 4 seconds) disables the tone squelch, and
permits monitoring of stations transmitting on the select-
ed channel while still keeping your receiver quiet from
noise ("MO" will appear at the top right of the LCD). Press
it again to only hear calls within your network.
Pressing and holding this button more than 4 seconds
toggles the tone and noise squelch override, allowing all
stations (and noise) on the channel to be heard. This may
be used to hear weak stations whose signals would not
normally open the squelch. Do this to pre-adjust the VOL-
ume control before receiving calls.
(With Selective Calling Option)
When the two-tone sequential decoder unit (F2D-5) is
installed, and a selective call has been received ("CALL"
indicator on), pressing and holding this button more than
2 seconds (but less than 4 seconds) will reset the call func-
tion on the current channel and silence the receiver, oth-
erwise pressing and holding this button more than 4 sec-
onds resets the call function on ALL channels.
( 2 ) PTT ( Push-To-Talk ) button
Hold this button to transmit (the "BUSY/TX" indica-
tor glows red).
( 3 ) LAMP/LOCK button
Press this button momentarily to illuminate the dis-
play for five seconds. Pressing and holding this button
locks top-panel push-buttons (S/DW, DISP, and the op-
tional DTMF keypad); this can be enabled to prevent ra-
dio settings from being disturbed.

for battery removal.
( 5 ) EAR and MIC Jacks
These jacks primarily intended for use with the op-
tional MH-45
External Speaker/Microphone. An exter-
E2B
nal earphone can be used in the larger jack, in which case
the internal speaker will be disabled. When these jacks
are not used, make sure the plastic cap and its two screws
are in place to protect the insides of the transceiver.

PERATION
Preliminaries
If the transceiver has not been used since leaving the
factory, fully charge the battery using VAC-520 Rapid
Desktop Charger before using it.
Mount the battery on the transceiver as described and
shown in the illustration below. Also, install the antenna
on the jack on top of the transceiver by screwing the con-
nector into the jack until it is finger-tight.
Battery Removal & Replacement
Make sure that the VOL control is set into the off
click-stop, and remove the protective soft or hard
case, if used.
Grasp the transceiver with your left hand, so your
palm is over the speaker and your thumb is on the
Battery Release Button.
Move the button in the direction indicated by the
arrowhead, while using your right hand to slide
the battery pack toward the side with the button.
The battery pack should slide smoothly out of its
track.
To replace the Ni-Cd pack, repeat the second and
third steps above, simply sliding the battery case
in the other direction after aligning the shorter side
of the battery pack with the track below the Bat-
tery Release Button.
