This field defines the time period that the user’s radio will remain
muted when dekeying following a secure transmission. In radio
systems having a large amount of data throughput delay, the tail end
of the user’s transmitted message could be heard following dekey if
this field is not set correctly to account for systems delays.
XL Transmit Use the UP/DOWN arrow keys to enable XL transmit mode for this
personality. This field configures the transmit mode of the XL chip. If
this feature is enabled, XL encrypted data will be transmitted in Secure
transmit mode. If this feature is disabled, Non-XL (Cipher Feedback)
encrypted data will be transmitted in Secure transmit mode. The
receive mode of the XL chip need not be configured since it will
automatically decrypt both XL and Non-XL data streams.
Scan Select Use the UP/DOWN arrow keys to specify whether the Secure scan
unsquelch duration for this personality is based on the XL or Non-XL
Scan Unsquelch Duration field in the RADIO WIDE SECURE OPTIONS
screen (F4/F3/F2/F6).
This field is visible if the field XL Transmit is Disabled. When scanning
for coded transmissions, the radio will wait for a Secure detect
following a carrier detect for a different duration depending on the
setting in this field:
Scan Holdoff Strapping This field is only visible if Rx voice/Signal Type on the Conventional
Personality screen (F4/F6/F3) is set to Non-ASTRO. Use the UP/DOWN
arrow keys to select the desired choice. This feature is used to optimize
the scan search algorithm and is normally based off on the receive
signal type desired during scan operation. The value selected will
determine the duration that the radio will wait on a channel for valid
signal activity during scan. Valid choices are:
Proper Code Detect Use the UP/DOWN arrow keys to enable proper code detect operation
for this personality. When this field is set to Enabled, the speaker will
unmute on secure data only if it is encrypted with the correct key.
Non-XL The radio will wait for the time period specified by the
Non-XL (Cipher Feedback) Scan Unsquelch Duration
field on the RADIO WIDE SECURE OPTIONS screen.
Non-XL&XL The radio will wait for the time period specified by the
XL Scan Unsquelch Duration on the RADIO WIDE
SECURE OPTIONS screen.

The radio will wait the preset time period specified for
the signal type specified in the RADIO WIDE
CONFIGURATION screen.
Both The radio will use the longest preset time period to
ensure that enough time is allocated to detect both
signal types.
