B110RB (COM610) Manual m/l 28/7/00 1:38 pm Page 1
Thank you for purchasing COMMTEL Brand (B110RB) wide
band monitor receiver.
Please read this operating manual to avoid misoperation of the
receiver. The B110RB is carefully designed but like all receivers
b110rb suffers from a degree of self-oscillation knows as
"birdies". These are from the nature of super heterodyne circuit
and are not representing a fault.
NOTE: Where text described in [SQUARE BRACKETS] the
keys are to be pressed exactly as shows.
For example: [8] [0] [0] [ENT]
Means press the numeric key 8, followed by the 0 key,
followed by the 0 key, followed by the ENT key.

Power requirement: B110RB can be operated from either
Ni-Cad. batteries, Dry cell batteries or external DC supply
of 9 - 6Vdc, 300mA minimum.
CAUTION: Do not attempt to connect B110RB directly
to the mains supply.
Very carefully note the polarity of the battery cells. Also
never attempt to charge the receiver or connect to an
external power source when dry batteries are in the
compartment. Always remove dry batteries when they
have run down and try not to use the B110RA for a period
of time and have dry batteries fitted, remove the batteries
to avoid leakage.
All memory channel data is stored into internal EEPROM
which does not require batteries or connection to external
supply. However always turn off the B110RB whenever
radio is not in use. Particularly turn off the B110RB while
