In Case of Trouble . ..
Most cases of erratic or improper operation can be
traced to one of three problems:
• Low battery voltage or poor battery connections.
• Poor antenna connections.
• A microprocessor "glitch" possibly caused by a
static discharge or other factors.
Checking the Battery Voltage
The battery voltage can be checked at any time using
the SET mode.

momentarily.
If
the battery voltage is low, the battery may need
recharging (FNB-52LI) or replacement (alkaline
cell). After recharging, you may need to wait for a
while to obtain an accurate voltage reading.
If the radio fails to tum on after replacing an alkaline
cell, remove the battery from the radio, and check it
with an external voltmeter. If the battery appears to
be OK, check the FBA-20 battery holder for dirty
contacts or some other factor which may be obstruct-
ing the flow of current from the battery to the radio.
Antenna Problems
The supplied antenna is very rugged, as is the SMA
connector on the transceiver. When using a different
antenna via an adapter, however, a poor connection
could degrade perforrnance.
If
you suspect an antenna problem and are using an
external or after-market antenna, try the original an-
tenna supplied with the transceiver to determine
whether the problem is with the other antenna.
Microprocessor Resetting
If
the transceiver behaves erratically, it may have
received a static pulse which has "confused" the mi-
croprocessor. Permanent damage probably has not
occurred, and you may only need to reset the micro-
processor to return the radio
to
its original defaults so
you can resume operation. Two levels of resetting are
available:
SET Mode Resetting
In some cases of confusing transceiver behavior, the
problem may lie in an improper setting in the Menu
System. To set the Menu System back to its original
factory defaults, without affecting other settings such
as the memories, use this procedure:
O
Tum the transceiver Off.
