Using Your Radio

Turning It On

Press and hold WX/POWER for at least two seconds to turn the radio

on. Press and hold WX/POWER again to turn the unit off.

Setting It Up

Even though you can change your radio’s settings at anytime, you will

probably want to establish initial settings after you have turned it on for

the fi rst time. You will adjust some of these settings on an as-needed

basis, but some settings might only need to be set once.

Changing the Volume

To change the speaker volume, press VOL/LOCK to enter Volume

Setting mode. 0 (for volume level 0 - 15) displays. Press CHANNEL UP

or CHANNEL DOWN to increase or decrease the volume levels. Press

VOL/LOCK to save.

Setting the Squelch level

The MHS155UV recognizes signals as transmissions if they exceed a

signal strength threshold.

Adjusting the squelch sets this threshold level. Increasing squelch

requires a signal to be stronger to be seen as a transmission. If you set

the squelch too high, you will risk not receiving transmissions that are

lower than that threshold. Reducing the squelch allows weaker signals to

be accepted.However, if you lower the squelch too much, you will hear

white noise all the time.
While listening to a channel, press and hold BAND/MENU to enter the

Menu. Press ENT/L/M/H till you enter the Squelch menu mode.The

Squelch level number displays on the LCD. Press CHANNEL UP or

CHANNEL DOWN to increase or decrease the squelch levels (0 - 3).

Press ENT/L/M/H to save the setting.
