to 12 volt DC, with a current capacity of 900mA.
2. Function:
A. Transmit and receive. The M538-BS will operate as a transceiver, meaning it will both
transmit and receive messages from other MURS radio units. The M538-BS is equipped to
operate on 5 channels, with 38 sub channels. In order to communicate with another MURS
radio, the channel and the sub channel must be set alike. The M538-BS also has 4 separate
call tones that can be used to page other users before starting a conversation. The M538-BS
can also receive an alert signal from the MURS ALERT transmitter. This will notify you of
activity at the location of the MURS Alert Transmitter.

tone that it had when it was turned off.
C. Earphone. The M538-BS is equipped with a jack for an earphone.
D. Relay Function. The red and black push button terminals on the back of the base station are
a Normally Open (NO) relay. The relay will make closure for several seconds when an alert
signal is received from the MURS Alert transmitter. The relay has a capacity of 5A @ 28V DC.
E. Operating range. The M538-BS is capable of communicating up to 2 or more miles. This will
vary depending on the local terrain.
