INTRODUCTION

Your STX Conventional Radio

One of the newest in a long line of quality Motorola
products, the STX Conventional radio is smaller, lighter,
and much more powerful than comparable radios.
What's more, results of our extensive Accelerated Life
Test indicate that the STX radio will also be far more re­liable and durable. Such features add up to better, more
cost effective two-way communications for you.

As a conventional only portable, this model of the
STX radio is designed to provide quality conventional
features for basic needs and special applications.

Your STX Conventional radio has an LCD display, a
two-position rotary control, a 15-button keypad, and an
on/off/volume rotary control. The two-position rotary
control allows you to select between repeater access
and direct (unit-to-unit) access on a per channel basis.
The 15-button keypad allows you to select channels and
to make and receive phone calls.

Basic Display Operation

1. When you're asked to press a specific button, press
it only as indicated. Don't hold it down unless told to
do so; otherwise, you may go right by the function
you want.

2. Normal use of the radio and display buttons will not
harm the radio. An alert tone indicates that the dis­played function is not accessible.

3. If for some reason you get off track, press the
MENU button until SYS is displayed below the sys-
tem number, then start again.

Proper Etiquette for Conventional Operation

In conventional operation, the STX radio performs

like other conventional portables. You must monitor a
channel before transmitting to make certain you're not
talking over someone who is already transmitting.

How to Recognize a Low Battery Condition

When your radio's battery needs charging, you get a
brief low battery warning (an alert tone that sounds like
a cricket "chirp-chirp") when you press and release the
PTT switch. You will hear this tone until you either
charge the battery or replace it with a freshly charged
one. The battery will operate for approximately 20 min­utes before failing.

In addition to the alert tone, the BATT annunciator
on the display will flash to indicate that you're radio's
battery needs charging.

How the Time-Out-Timer Works

Each radio is equipped with a time-out-timer preset
at 60 seconds. This timer cuts off radio transmissions
when they exceed the transmitting time allowed. A
warning tone (low frequency "yell") indicates that trans­mission will be cut off in 4 seconds.

How to Lock/Unlock the Keypad

You can lock the keypad to prevent accidentally
changing your system/subfleet position. Press MENU
until LCK appears on the display. If it is flashing, the
keypad is not locked. Press STEP to lock it; LCK will be
on solid. Press STEP again to unlock it; LCK will be
flashing again.

How to Mute/Unmute Keypad Tones

You can turn the keypad tones ("chirp") of your STX
radio off and on. Press MENU until SUB is displayed.
Press 1 ( ) on the keypad. If the tones were "on,"
pressing 1 ( ) will turn the tones off. If you press any
other key you will notice that there is no "chirp." Press 1
( ) again to turn the keypad tones back on.

Your STX radio will always remember if the keypad
tones are "on" or "off," even when you turn the radio off.
