Failure to include this option when using an intrinsically safe battery is characterized by a
premature indication of a low-battery condition. For SABER I radios (no display), this option is
only required when option H906 (low battery LED) is selected.
H958 - Unit ID - MDC 600
Selecting this option defines an MDC 600 ID to the radio, where 600 refers to a 600 baud rate.
The portable user can send out his unit ID whenever PTT is activated, deactivated, or both. There
will be one unit ID per radio channel. The transmission of the user's ID will allow the base
operator to track voice communications on a given channel. Sidetones will be heard (if enabled)
while the ID is being transmitted. You can enter a 4 digit hexadecimal ID in the range from 0001
to DEEE, excluding any occurrence of a hexadecimal F. Trailing Unit ID is not available on secure
radios.
H959 - Unit ID - MDC 1200
Selecting this option defines an MDC 1200 ID to the radio, where 1200 refers to a 1200 baud rate.
This option's description is identical to that of MDC 600 (H958) except for the baud rate
of 1200.
H961 - Unit ID and Emergency - MDC 600
This option allows you to enter a unit hexadecimal ID for MDC 600 in the range from 0001 to
DEEE, excluding any occurrence of a hexadecimal F. By pressing the emergency button located
on the top panel of the radio, the radio goes to the preprogrammed emergency channel and sends
out an alarm. If emergency is transmitted while scan is running, the emergency opcodes will go
out on the channel that a transmit last occurred (this may or may not be the home channel).
H962 - Unit ID and Emergency - MDC 1200
This option behaves identical to Unit ID and Emergency - MDC 600 (H961) except that it
functions at 1200 baud. This option is incompatible with scan options H273 and H344.
H963 - Unit ID W/ Audible Emergency - MDC 600
This option allows you to enter a unit hexadecimal ID for MDC 600 in the range from 0001 to
DEEE, excluding any occurrence of a hexadecimal F. You can go to the preset emergency
channel by pressing the emergency button located on the top panel of the radio. When the
emergency button is pressed, the radio sends out the emergency sequence and simultaneously
generates side tones each time the sequence is transmitted. The radio will remain on the
emergency channel unless you press PTT to transmit. If emergency is transmitted while scan is
running, the emergency opcodes will go out on the channel that a transmit last occurred (this may
or may not be the home channel).
H967 - Unit ID W/ Audible Emergency - MDC 1200
This option behaves identically to Unit ID W/ Audible Emergency - MDC 600 (H963), except that
it functions for 1200 baud. If emergency is transmitted while scan is running, the emergency
opcodes will go out on the channel that a transmit last occurred (this may or may not be the home
channel).
H923 - Unit ID W/Emergency Revert - MDC 600
This option allows you to enter a unit hexadecimal ID for MDC 600 in the range from 0001 to
DEEE, excluding any occurrence of a hexadecimal F. By pressing the emergency button located
on the top panel of the radio, the radio goes to ghe preprogrammed emergency channel, one for
each zone, transmits a silent alarm, and then reverts back to the channel that you were on. A total
of 20 emergency packets are sent each time emergency is pressed. This option is incompatible
with H707.
H946 - Unit ID W/Emergency Revert - MDC 1200
This option behaves identically to Unit ID W/Emergency Revert - MDC 600, except that it
functions for 1200 baud. This option is incompatible with H707.
No Channel Re-Revert After Emergency – Selecting this option will cause the radio to remain
on the reverted channel after the completion of the emergency packet transmissions. Any
subsequent transmissions will be sent out the assigned Emergency Revert channel. Cancelling
this may be done by manually changing channels or by resetting the radio.
