Radio Operation With Features; General; Coded Squelch Operation; Variable Rf Power - Motorola JT 1000 User Manual

General

All discussions of radio features assume specific combinations of the 3-
position toggle switch, side button programming, and radio model capability.
Your particular radio operation may vary depending on these choices.

Coded Squelch Operation

Tone Private-Line (PL), Digital Private-Line (DPL), and carrier squelch
operation are all available in the same radio, on a per-channel basis. When
operating in carrier squelch mode, all traffic on that channel is heard. When
operating PL or DPL, your radio hears those messages intended for you. When
this feature is channel-slaved, PL, DPL, or carrier squelch is programmed to
each transmit and receive frequency, and you need not move any switches for
activation. Alternatively, this feature can be programmed to the 3-position
toggle switch. See Table 2 toward the rear of this manual.

Variable RF Power

Transmit power on JT 1000 radios is programmed on a per channel
basis, one or more channels (as required) for high power and other channels
for low power. Programming of this feature can be done by:
• the user, via the keypad and display (see page 15), or by
• Radio Service Software.
Note: Unless programmed otherwise by Radio Service Software, JT 1000
radios will transmit low power only when using an alkaline battery.

Programmable Features

The JT 1000 Radio uses the display and keypad to give you quick access
to the following features, programmable per channel:
• multi-selectable PL/DPL/CSQ,
• squelch level adjust, and
• power selection.
Important Note: While programming any one of these features, all transmit
and receive functions are disabled.
Once the radio is turned on and the HOME display
is shown, pressing either the left (
arrow key ( ) prompts the radio to show two softkey
features (SQL and PWR) on the 14-character display,
with key-like outlines, known as "softkeys," to make them look like keys.
Selecting the SQL or PWR feature is accomplished by pressing the softkey
button directly below it. The softkey buttons (
keys on the keypad. The left key controls the left feature and the middle key
controls the middle feature. For detailed information, refer to "Adjust Squelch
(SQL)" and "Select Power (PWR") paragraphs on page 15.
