Use the UP/DOWN arrow keys to enable XL transmit mode for this
personality. This field configures the transmit mode of the XL chip.
When set to Enabled, XL encrypted data will be transmitted in
SECURE transmit mode. When set to 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.
The default is Enabled.
Use the UP/DOWN arrow keys to select the secure scan unsquelch
duration for this personality. When scanning for coded transmis-
sions, this field is used to select the amount of time the radio will wait
for a SECURE detect following a carrier detect. If set to Non-XL, the
radio will wait for the time period specified by the Non-XL (Cipher
Feedback) Scan Unsquelch Duration field in the RADIO WIDE
SECURE OPTIONS screen. If set to Non-XL&XL, the radio will wait for
the time period specified by the XL Scan Unsquelch Duration field in
the RADIO WIDE SECURE OPTIONS screen.
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. When set to either Clear
Only or Secure Only, the radio will wait the preset time period
specified for the selected signal type. When set to Both, the radio will
use the longest preset time period to ensure that enough time is
allocated to detect both signal types.
The factory default is Both.
This field applies only to SECURE radios. The value in this field should be
based on the expected receive data format for the personality. This
field allows the user to configure the radio's personality for:
Strictly binary (two-level) receive operation;
Strictly multi-level (four-level) receive operation; or
Both binary and multi-level receive operation (Auto Receive).
When operating in Auto Receive mode, the radio will automatically
detect the received signal type and process the data accordingly. Two-
level sensitivity is reduced when operating in the Auto Receive mode and thus
should not be used on channels or systems that are strictly binary (two-level).
The factory default is 2 Level Receive.
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.
The factory default is Enabled.
Use the UP/DOWN arrow keys to select the echo mute time for this
personality. Values between 0 and 1500 ms may be selected in 50 ms
increments. This field defines the time period that the user's radio will
