M538-HT(Handheld)

Operating instructions

1. Power Supply: The M538-HT is powered by 6 AA rechargeable batteries. The batteries can be charged in the unit

by using the plug in transformer that is provided. The battery icon on the LCD will display the amount of battery

charge. One bar showing on the icon will mean that the batteries need to be charged, three bars on the icon mean

that the batteries are fully charged.

Note: ONLY use the charger with rechargeable batteries. When the charger is plugged in, the unit will receive

signals but will not transmit.

2. Function:

A. Transmit and receive. The M538-HT will operate as a transceiver, meaning it will both transmit and receive

messages from other MURS radio units. The M538-HT 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-HT also has 4 separate call tones that can be used to page other users before starting a conversation. The

M538-HT 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.

B. LCD Display. The LCD will display channel, CTCSS, Tone, TX, RX, Lock Icon(**), and Alert Icon(**). When the

base station is powered up, it will return to the same channel, CTCSS, and Tone that it had when it was turned off.

C. Earphone. The M538-HT is equipped with a jack for an earphone.

D. Operating range. The M538-HT is capable of communicating up to 2 or more miles. This will vary depending on

the local terrain.

E. Power save mode. If the unit has not received or transmitted a signal for more than a minute, it will go into power

save mode. This will extend the life of the batteries. When a signal is received or transmitted, the unit will

automatically go out of power save mode.

3. Operation:

A. ON/OFF/Volume. With the batteries charged, you can turn the power on or off by rotating the knob on top of the

M538-HT. This will also control the level of the volume.

B. Changing Channels. You can select the proper channel by pressing the up or down key. The lock Icon(**) must

be deactivated before you can change the channel.
