10) Cloning
For compatibility with current models of TEKK, the data of those models (such as channels, tones, 5-

5
tone ID, etc.) are cloned to another radio with Cloning cable. .
11) Voice Operated Transmit(VOX)
Enjoy the convenience of hands-free operation when used with optional accessories.
12) PC Programming and Tuning
Radio parameter programming and tuning can be accomplished via the accessory connector from a
PC-compatible computer without ever having to open the radio to save both time and expense
(requires optional programming JIG and software)
13) Flash Memory Advantage
Flash memory permits updates, advanced feature sets and system architectural changes to be made

5.1 Safety Notes
1) The radio of XV/XU series receives power from high-performance Li-ion battery
(XSB-1800). XSB-2400 Battery is safe of high performance and highly reliable, and could be
charged very fast. XSB-2400 Battery has been designed suitably only for the charger of Tekk
(WLB-100).
The charging of the enclosed Radio on the other maker’s charger will
cause a damage on the battery and also, will cause a trouble on the
Radio.
2) Please charge the battery before using the radio for best performance and safety.
3) When you charge the battery that is installed in the Radio, please turn off the radio first to charge
the battery.

13
The continuous rapid discharge (for example, when making a short circuit
on the ‘+’ terminal of battery by a metal substance) may make a fatal
defect and the battery can be exploded. Also, it can cause a fire.
4) Using the correct battery will improve the efficiency and safety.
5.2 The Time of Charging
Low battery voltage will make the radio less coverage and also make the performance worse. Please
charge the battery in case of following:
When you think performance of the radio becomes lower
When the red lamp on RX/TX Led blinks (every 0.5 second) during transmission or reception
When the battery icon blinks
4) When “beep” sound is generated while the radio is in use.

general mode, the Radio will be converted to the call mode automatically.
Ffigure 6-9) ID Transmission
③ After the call is completed, the Transmission and the Reception have no restriction, which
means that the TX/RX will be free.
2) 2) Group(1:N) Call at call mode
① In order to make the Group call at the call mode, the following should be set up at the PC
programming.
② If the 1st party (ID:53579) and the 2nd party(ID:52468) are in one group, the "5AAAA"which is
a call number / call name(example : baseball player) should be designated. ("A" means that all
the numbers are applied.)

19
3) If the caller makes a call to the group of baseball players, the caller’s Radio should press the
“Menu” and “▲” buttons at the same time after selecting the party with ID “1AAAA”. In this case,
the Radios of the party1 and the party2 display the ID "1AAAA". In case of the group call, the
party’s Radio displays the group ID number.
After the call is completed, the Transmission and the Reception have no restriction, which
means that the TX/RX will be free.
Figure 6-10) Group Call
3) RESET
This Reset function converts the TX/RX with no restriction to the previous Close mode. Press the
Monitor button (M) at the call mode.
①The call signal will be transmitted to the party’s Radio with the ID number + “C” tone.
② If the party’s Radio is in the Close channel and after receiving the call with the “C” tone, the
call is converted to the “TX/RX with no restriction” mode.
6.9 Emergency Call function
1) This Emergency call is used for calling the party in emergency and if pressing for about 2 seconds
