Repeat Mode In this version, you will NOT be able to change the setting for the VRS-EP
Repeat Mode feature. The Repeat Mode option indicates the manner in
which the VRS-EP will repeat or re-transmit signals to the portable
radios within the area of operation. Where more than one VRS-EP unit
will be involved (Multi-unit VRS-EP operation), all participating units
must be programmed with the same Repeat Mode. The available
settings for this feature are:
Access Ack and TOT Tones Use the UP/DOWN arrow keys to enable/disable the Vehicular
Repeater System—Expanded Protocol (VRS-EP) Access Ack and Time-
Out-Timer (TOT) Tones. If this option is enabled, the VRS-EP unit will
transmit a high-pitch tone after it has successfully received a message
that can be repeated from a portable unit. This tone is sent to the
portable radio and is heard by the user of that radio. If the
transmission is not successfully completed before the Time-Out Timer
(TOT) expires, a lower pitch tone will be heard instead.
Note: The user of a portable may not hear either tone after
completing a transmission if the user happens to be out of the
range of the VRS-EP unit.
If this option is disabled, the user of the portable radio will not get any
acknowledgment tones of either successful or unsuccessful
transmissions.
Trunking Access Tones Use the UP/DOWN arrow keys to enable/disable this feature. If this
feature is enabled, the Vehicular Repeater System—Expanded Protocol
(VRS-EP) unit will transmit a high-pitched tone after successfully
receiving a repeatable message from a portable unit. This tone will be
sent to the portable radio and will be heard by the user of that radio.
If the transmission could not be successfully completed for some
reason, a low-pitch tone will be heard instead. If this field is disabled,
the tones described above will not be heard.
Note: Even if this feature is enabled, these tones will not be heard if
the portable radio is out of range of the VRS-EP unit. However, this
feature will not affect Talk Permit, Talk Prohibit and System Busy
tones. These tones are constantly active and will be heard by the
user of the portable radio.
Mobile Audio
Repeat
The VRS-EP repeats any signal received and heard on the
mobile radio. The user of the mobile radio may turn on
the radio monitor to allow incoming base signals with
any PL tone or DPL code to be heard by the portable
radio users in the area. Turning the monitor off will
prevent all base-to-portable signals from being heard
unless the mobile radio’s coded squelch (PL/DPL)
requirements are met. Note that taking the mic off the
radio HUB (Hang-Up Box) will have an effect on the
radio similar to that of an activated monitor.
Mobile PL
Decode
The VRS-EP repeats base-to-portable transmissions only
when the signal includes the correct PL tone or DPL code
regardless of what is heard on the mobile speaker. For
correct operation, PL or DPL must be programmed on the
mobile modes for which base-to-portable signal repeats
are to be regulated in this manner.
