PREPARATION
INSTALLING/ REMOVING THE BATTERY PACK
The battery pack is not charged at the factory; charge it before use.
1Align the battery pack with the back of the
transceiver, then press the battery pack and
transceiver firmly together until the release latch on
the base of the transceiver locks.
2To remove the battery pack, lift the safety catch on
the base of the transceiver, then press the release
latch underneath the safety catch.
3While pressing the release latch, pull the battery
pack away from the transceiver.
CAUTION
◆Do not short the battery terminals or dispose of the battery by fire.
◆Never attempt to remove the casing from the battery pack.
◆Do not remove the black sheet from the reverse side of the transceiver (refer
to the illustration below). Removal of this sheet decreases the waterproof
efficiency of the transceiver and may cause malfunctions if water seeps into
the transceiver.
◆Use KNB-84L battery pack (Supplied battery) to maintain IP67 performance.

5
INSTALLING THE ANTENNA
Screw the antenna into the connector on the top of the
transceiver by holding the antenna at its base and turning it
clockwise until secure.

INSTALLING THE BELT CLIP
If necessary, attach the belt clip using the two
supplied M3 x 8 mm binding screws.
Note:
◆If the belt clip is not installed, its mounting
location may get hot during continuous
transmission or when left sitting in a hot
environment.
◆Use the Phillips #2 screwdriver.
Belt clip
M3 x 8 mm
screws
CAUTION
◆Do not use glue which is designed to prevent screw loosening when installing
the belt clip, as it may cause damage to the transceiver. Acrylic ester, which
is contained in these glues, may crack the transceiver’s back panel.

6
INSTALLING THE CAP OVER THE SPEAKER/ MICROPHONE JACKS
Note:
◆For the speaker/ microphone jack, waterproof performance is guaranteed by
securing the supplied cap. Waterproof performance will not be guaranteed by
connecting an optional speaker/ microphone, etc.
◆Use the Phillips #1 screwdriver.
1If you are not using an optional speaker/
microphone or headset, install the cap over the
speaker/ microphone jacks.
2Secure the cap in place using the attached screw.

INSTALLING THE SPEAKER/ MICROPHONE OR HEADSET
Note:
◆Use the Phillips #1 screwdriver.
1Insert the speaker/ microphone plugs into the
speaker/ microphone jacks of the transceiver.
2Place the locking bracket over the speaker/
microphone plugs so that the locking tabs insert
into the transceiver grooves.
3Secure the locking bracket in place using the
attached screw.

OPERATOR SELECTABLE TONE (OST)
You may have programmed CTCSS or DCS signaling on your transceiver
channels. A CTCSS tone/ DCS code is a sub-audible tone/code which allows you
to ignore (not hear) calls from other parties who are using the same channel.
When a channel is set up with a CTCSS tone or DCS code, squelch will only open
when a call containing a matching tone or code is received. Likewise, signals that
you transmit will only be heard by parties whose CTCSS/ DCS signaling matches
your transceiver.
OST FUNCTION ON/ OFF
1Select your desired channel using the Selector.
2Press the [ <B ] button to turn the OST (Operator Selectable Tone) function
ON and OFF.
• A dot appears in the bottom right side of the display when the OST
function is turned ON.
OST SETTINGS
1Select your desired channel using the Selector.
2Press and hold the [ <B ] button to enter OST setup mode.
• “OST” appears, followed by the current setting.
3Press the [ <B ] or [ C> ] button to select the desired CTCSS frequency or
DCS code.
• Refer to the tables {p. 15} for the full list of CTCSS frequencies and DCS
codes.
4Press the [ S ] button to set the selected CTCSS frequency or DCS code, and
exit OST setup.
5Operate the transceiver as normal to make and receive calls.
• Ensure that all other members in your group are operating on the same
CTCSS/ DCS setting.

15
Note:
◆The OST function will not work on channels 5 and 35 (emergency channels).
◆If the OST function is used on channels 22 and 23, only the decoding values
will be set. Encoding values will not be set, as transmission is inhibited on
these channels (data channels).

SCAN
Scan monitors for signals on the transceiver channels. While scanning, the
transceiver checks for a signal on each channel and only stops if a matching
signal is present.
To start/stop scanning, press the [S]button.
• “SCAN” appears and the “ ” indicator appears during Scan.
• When a signal is detected, Scan pauses at that channel. The transceiver will
remain on the busy channel until the signal is no longer present, at which time
Scan resumes.
Note:
◆To use Scan, there must be at least 2 channels added to the scanning
sequence.
SCAN DELETE/ADD
You can add and remove channels to and from your scan list.
1Select your desired channel.
2Press the [ ] button to add or remove the channel.
• The “ ” indicator appears when the selected channel is added to the scan
sequence.

ACCESSIBLE FUNCTIONS
FUNCTION MODE
Your transceiver operations vary according to the functions that your dealer has
programmed to the transceiver buttons. Refer to “FUNCTIONS LIST” {p. 19 }
for the available programmable functions.
MENU MODE
Many functions on this transceiver are selected or configured through the Menu
instead of physical controls. Once you become familiar with the Menu system,
you will appreciate the versatility it offers.
Some transceiver buttons may already be programmed with functions listed in
the Menu. Those functions can be accessed directly by pressing the button.
All other functions can still be accessed using the transceiver Menu. Refer to
“FUNCTIONS LIST” for the available Menu items.
• Menu Mode can register functions by category (Up to 12 categories).
Example:
Category Function
CALL Autodial
SCAN Scan, Scan Delete/Add
AUD/TONE Squelch Off, Squelch Level
• The category does not appear in Menu Mode when only one category is
configured. When the transceiver enters Menu Mode, the functions registered
in Menu Mode appear.
Menu Access
1Press the button programmed as [Menu].
• The category list is shown.
• When there is only one category, the function list is shown (proceed to step 4).
