Using The External Speaker/Mic Jack; Using The Battery Save Feature - Uniden MHS127 Owner's Manual

Using Your Radio

Using the external speaker/Mic jack

You can connect an optional external speaker-mic to this watertight jack.
Unscrew the cap, which is held by the rubber cap-keeper to prevent loss.
Insert the special gasketed plug and screw down the shell, which prevents
water from entering the jack.
For details, consult your dealer or contact Uniden Customer Care directly
(see front cover for contact information).

Using the Battery Save feature

The Battery Save feature automatically turns off receive power at regular
intervals to save battery power. Battery Save turns off when receiving
transmissions or transmitting a response. It reactivates after 3 seconds of no
activity (transmit or receive).
Battery Save does not work while in Scan mode or in Triple/
Dual watch.
