Radio Operation
with Features (cont.)
Time-Out Timer
Time-out timer is a per-channel feature that limits the amount of time you
can continuously transmit on a channel. If you hold down the PTT longer than the
allotted time:
•
a pre-alert warning tone will be generated four seconds prior to
termination of the transmission to give you an indication that your
conversation is about to be cut off.
•
the transmission is terminated at a selected time (pre-programmed by
Radio Service Software) and an alert tone is heard until the PTT is
released.
Note: The time-out timer function ships disabled from the factory. When activated
using Radio Service Software, the default time is 60 seconds
PAC•RT™
PAC•RT is a per-channel feature that allows you to communicate with the
mobile vehicular repeater system, transmitting through a PAC•RT vehicular
repeater (for increased power) to the base station. When you select PAC•RT
operation, all messages are communicated portable-to-base. In radios with
PAC•RT programmed to the 3-position toggle switch, if the (B) or (C) position of
the 3-position toggle switch is selected, all messages are communicated portable-
to-portable, and the PAC•RT repeater is not activated. See Table 2 located toward
the rear of this manual.
Note: PAC•RT ships disabled from the factory.
Receive-Only Channel
JT 1000 radios can be programmed to operate receive-only on a per-channel
basis. A channel programmed for receive-only will not transmit. Pressing the PTT
will result in a low-pitch alert tone.
Single Tone
™
Signalling
Single Tone is an "encode-only" signalling feature programmed by radio
service software. With this feature a timed tone is transmitted with the push of a
button. The feature is programmed to the PTT switch or to any of the three side
buttons. A maximum of two different tones can be programmed, each to any one
of the four buttons (PTT, SB1, SB2, or SB3). If one of two single tones is
programmed to the PTT switch, it must be single tone one.
