In Car Monitor Default In this version, you will NOT be able to change the setting for this feature.
The In-Car Monitor (ICM) Default feature allows the selection of an
operational mode for use in Vehicular Repeater System—Expanded
Protocol (VRS-EP) activities during which a party remains in the
vehicle. In such activities, the user who remains in the vehicle with the
VRS-EP is given a certain set of transmission capabilities depending on
the ICM Default selection. Valid options for this feature are as follows:
Operator Select ICM In this version, you will NOT be able to change the setting for this feature.
Use the UP/DOWN arrow keys to enable/disable the Vehicular
Repeater System—Expanded Protocol (VRS-EP) Operator Select ICM
feature.
This feature allows the user of the mobile radio to change the ICM
setting by entering into a radio configuration state. When the
Operator Select ICM feature is enabled, an extended press of the VRS-
EP button puts the radio into this ICM configuration state. The ICM
types can then be browsed using the radio’s Mode Up/Down buttons.
The desired ICM may be locked in with a press of the Home button.
ICM PPI In this version, you will NOT be able to change the setting for this feature.
Use the UP/DOWN arrow keys to enable/disable the In Car Monitor
Portable Priority Interrupt (ICM PPI) option. If this option is enabled,
portable-to-base transmissions take priority over mobile radio
transmissions. The user of a portable radio will be able to transmit
even if the mobile radio was previously keyed up and was in use by a
party remaining in the vehicle.
Repeater PPI Use the UP/DOWN arrow keys to enable/disable the Repeater Portable
Priority Interrupt (Repeater PPI) option. The Repeater PPI option,
when enabled, causes any on-going transmissions from base to the
portables to be interrupted if any portable radio user keys up. This
option should be enabled if it is desirable that all portable unit
operators be able to break into base station transmissions. A clicking
sound heard on the portable radios is normal and unavoidable with
Repeater PPI operation.
Base Allows the mobile radio to transmit (when the PTT button is
pressed) on the frequency corresponding to the mode on the
control head’s display. This transmission will not be heard by
the user of the portable radio.
Port Allows the user of the mobile radio to transmit to the
portables in the area of operation, but not to the base. The
VRS-EP Tx PL frequency option must be set to match the portables’
receive PL frequency. If the mobile radio’s PTT button is pressed
during an on-going portable-to-base activity, the attempted
transmission is blocked, resulting in an audible talk-prohibit
tone on the mobile radio.
Both Allows the mobile radio to transmit on the frequency
corresponding to the mode on the control head’s display and
the portable frequency simultaneously. The VRS-EP Tx PL
Frequency option must be set identical to the portable unit’s
Receive PL Frequency. Again, if the mobile radio’s PTT button is
pressed during an on-going portable-to-base activity, the
attempted transmission is blocked and an audible talk
prohibit tone is heard on the mobile radio.
