the signal required. Squelch also affects operating distance. Unless you run into extreme
conditions where you need more or less operating range than normal, we recommend
keeping the squelch around the factory setting of +15.
DISPLAY
There are two default options for the LCD screen: FREQUENCY˝ or CHAN˝. Additionally,
you have a choice of displaying either SQ˝ (squelch) or LEVEL˝ settings. Activate the
menu screen and scroll to DISPLY˝. Press SET and FREQUENCY˝ will flash. Press the UP
button and CHANNEL˝ will flash. Press the UP button and SQ˝ (squelch) will flash. Press
the UP button and LEVEL˝ will flash.
Once you decide whether you want Frequency˝ or Channel˝ as the default, press SET to
save it. If you choose Frequency˝, the receiver frequency will be displayed as the default. If
you choose Channel˝, then Group/Channel˝ will be displayed as the default.
Hint: If Frequency˝ is selected as the default, then by pressing the SET button quickly, the
Group/Channel˝ info will be displayed for a few seconds. If Channel˝ is selected as the
default, then by pressing the SET button quickly, the Frequency˝ will be displayed for a
few seconds.
The option of showing either Level˝ or Squelch˝ is also available. Whatever settings are chosen
for those items will be displayed once selected and saved. Level˝ is the factory default.
LOCK
You can lock the receiver to prevent someone from accidentally pressing SCAN, SYNC or
the POWER button. Once everything is set and working, this is recommended.
Locking Feature For AP42
In order to insure that someone does not change a Group unintentionally, there is a Lock
feature added to the AP42. Scroll through the menu to the LOCK˝ screen and choose lock
ON.˝ This will disable the SCAN, SYNC, SET, UP, and DOWN buttons. To unlock the receiv-
er, scroll through the menu to the LOCK˝ screen and choose lock OFF˝. All functions will
be enabled.
PILOT
This is an inaudible tone generated by the transmitter to the receiver as additional
insurance to keep the receiver from generating noise when there is no signal present.
The Pilot should be left ON and only be turned OFF temporarily if troubleshooting the
system for problems.
