precautions.

z If the mobile radio is not properly installed, road shock could bump the radio loose,

and the falling radio could, in some circumstances, cause serious injury to the driver

or a passenger. In case of vehicle accidents, even when properly installed, the radio

could break loose and become a dangerous projectile.

z Antenna mounting: The antenna supplied by the manufacturer or radio dealer must

not be mounted at a location such that during radio transmission, any person can

come closer than the above indicated minimum safe distance to the antenna (i.e. 82

cm/32inches).

z To comply with current FCC RF Exposure limitations, the antenna must be installed at

or exceeding the minimum safe distance indicated above. and in accordance with the

requirements of the antenna manufacturer or supplier.

z Vehicle Mounting: The antenna can be mounted at the center of a vehicle metal roof

or trunk lid if the minimum safe distance is observed.

Scan

■ Scan Type

1. Single Zone Scan

Radio scans all the channels that added into the scan list on the current zone.

2. Multi Zone Scan

Multiple zones that added into a multi scan list can be scanned. All channels within all

the zones that added into the scan list can be scanned.

■ Scan Start

1. Add one or several non-priority channels into the scan list.

2. Press the programmed Channel Scan key to initiate scan from the current channel,

and ascends through the channel numbers in scan list. The LCD displays the “SCAN”

icon (“-SCAN-” indicates multi zone scan).

■ Scan Cease

Scanning pauses or ceases upon the following:

1. Upon repress the programmed Channel Scan key, scanning ceases, and the radio

exits the scan mode.

2. Activate the Monitor function.

3. Receives carrier that satisfy radio un-mute condition.

■ Scan Resume

If scanning pauses on an active channel, the scanning will resume according to the scan

resume mode. The scan resume mode is programmable by your dealer for Carrier

operated scan or time operated scan.

17

1. Time Operated Scan

Scanning remains on an active channel for a programmed time period (programmable

by your dealer),once the timer expires, the radio will begin scanning other channels

even if the active channel is still busy.

2. Carrier operated scan

If carrier is detected during the scan sequence, scanning will remain on the active

channel until here is on activity.

■ Dual Priority Scan

If dual priority channels are programmed by your dealer, the radio still checks the dual

priority channels for activity at configured intervals. While scanning pauses on a

non-priority channel. If carrier is detected on a priority channel, the radio will

immediately switch to the active priority channel.
LCD displays the “p。” icon if the current channel is programmed as the Priority Channel

1. the “p.” icon if the cur-rent channel is programmed as Priority Channel 2, while the “p.”

icon if the current channel is programmed as both the Priority Channel 1 and 2.

■ Scan Add/Delete

If the Scan Add/Delete feature is enabled by your dealer, the current channel can be

added/deleted to/from the scan list, as the following procedures.

1. Select a channel to be added/deleted in the non-scan mode.

2.The current channel toggles between Add/Delete status upon each press the

programmed scan Add/Delete key.

Note: Only channels that added into the scan list can be scanned.

■ Nuisance Channel Delete

Temporarily deletes a specific channel from your scan list during the scan sequence.

When scan pauses on an unwanted channel such as a noise channel, press the

programmed Add/Del Scan key to temporarily deleted the channel from the scan list,

then scanning reinitiates immediately.

Note: the temporary delete is not memorized once radio exits from scan mode.

■ Revert Channel

Upon pressing the [PTT] during scanning, the radio will pause scanning and switch to

the Revert Channel to transmit. This feature is programmable by your dealer.

time period, the signalling squelch is enabled.

Off Hook Decode

If the feature is enabled by your dealer, CTCSS/CDCSS signalling is active no matter the

microphone is in the off/on hook condition. If the feature is disabled, CTCSS/CDCSS

21

signalling is disabled while the microphone is in the off hook condition.

Busy Channel Lockout (BCL)

The feature can be enabled/disabled by your dealer, this feature is to prevent transmission

on a channel that is already in use. Press the [PTT] on a channel that is already in use,

transmission is inhibited and an alert tone is heard . upon release the[PTT], the alert tone

ceases and radio returns to receive mode. Press the [PTT] to transmit while the channel is

free.

0.5s to override the BCL feature and BCT feature and transmit on the busy channel.

Time-out Time (TOT)

■ Time-out Time (TOT)

The feature allows for more efficient use of channels by limiting the maximum time of each

transmission. It protects the radio from damage caused by long time transmission. Once a

continuous transmission exceeds the preset time.

(15～1200s programmable), the transmission is automatically terminated and alert tone is

heard. The alert tone ceases upon release the[PTT].

The TOT default is 180s, it meets normal operation needs. Any change should be

permitted by professional technicians.

■ TOT Pre-alert

The radio has a TOT Pre-alert timer. The radio will emit the Pre-alert tone at the
programmed time (1～10s before the TOT timer expires).

■ TOT Re-Key Time

The radio has a TOT Re-Key timer. Since transmission is terminated upon the TOT timer

expires, the TOT Re-key timer is activated, and transmission is inhibited if press the [PTT]
before the expiration of TOT Re-key timer (programmable by your dealer as Off,1～60s).

■ TOT Reset Time

The TOT Reset timer is activated upon release the [PTT]. While the TOT timer will not

reset until the TOT Reset timer expires. Press the [PTT] before the TOT Reset timer

expires, the TOT timer continues to countdown.
The TOT Reset Time is programmable by your dealer as Off,1～15s.
