Enter the desired value directly or use the UP/DOWN arrow keys to
make your selection. When an MDC signal is detected and then lost,
the radio will not immediately unmute for voice. A time delay
specified in this field will be executed first. During this delay period, if
the MDC signal is detected again, the radio will remain muted and this
timer will be terminated and reset. This timer will help prevent
temporary loss of DOS mute in areas of poor signal strength or high
multi-path distortion. The valid range is 0 (zero) to 500 ms in 10-ms
increments.
Note: Setting this field to 0 (zero) implies that the timer has
been Disabled.
The default is 40 ms.
Enter the desired value directly or use the UP/DOWN arrow keys to
make your selection. This is the time period for which the radio will be
muted automatically after Carrier Detect on an MDC decode channel.
This timer is necessary since MDC data cannot be detected instantaneously,
and the DOS mute function operating without this timer will usually allow
a small "squeak" of data to be heard through the speaker.
This timer should be set to as low a value as possible while still muting
the entire MDC transmission. When this timer is set to a non-zero
value, DOS Mute will automatically be enabled. When it is set to 0
(zero), DOS Mute will automatically be disabled. The range is 10 to
2550 ms in 10-ms increments. A setting of Disabled is also available.
The default is 550 ms.
This field is applicable to HT 1000 model radios only and require that the
radio be equipped with the appropriate Mandown Switch accessory. Enter
the desired value directly or use the UP/DOWN arrow keys to make
your selection. This is the time delay between closure of the Mandown
Switch and initiation of the Mandown Alert Tone which can be set
from 0 (zero) to 8 seconds in one-second increments.
Note: Mandown delays can be used if you want to allow the
radio user to correct an accidental tipping or fall of the radio.
The default is 5 seconds.
This field is applicable to HT 1000 model radios only and require that the
radio be equipped with the appropriate Mandown Switch accessory. Enter
the desired value directly or use the UP/DOWN arrow keys to make
your selection. This is the time delay between the initiation of the
Mandown Alert Tone and the actual transmission of the emergency
alarm sequence. This delay can be set from 0 (zero) to 8 seconds in one-
second increments.
Note: Mandown delays can be used if you want to allow the
radio user to correct an accidental tipping or fall of the radio.
The default is 5 seconds.
