1 SUPPLIED ACCESSORIES After carefully unpacking the transceiver , identify the items listed in the table below . We recommend you keep the box and packaging for shipping. A market area code (K, E, M2, or M3) can be found on the label attached to the package box.
2 1 PREP ARA TION 2 Position the transceiver , then insert and tighten the supplied hexagon SEMS screws (4) and flat washers (4). •D ouble check that all hardware is tightened to prevent vehicle vibration from loosening the bracket or transceiver .
3 1 4 Confirm the correct polarity of the connections, then attach the power cable to the battery terminals; red connects to the positive (+) terminal and black connects to the negative (–) terminal. •U se the full length of the cable without cutting off excess even if the cable is longer than required.
4 1 2 Connect the transceiver ’s DC power connector to the connector on the DC power cable. •P ress the connectors firmly together until the locking tab clicks. Note: ◆ For your transceiver to fully exhibit its performance capabilities, we recommend using the optional PS-33 (20.
5 1 R EPLACING F USES If the fuse blows, determine the cause, then correct the problem. After the problem is resolved, replace the fuse. If newly installed fuses continue to blow , disconnect the power cable and contact your authorized KENWOOD dealer or an authorized KENWOOD service center for assistance.
6 1 ACCESSORY CONNECTIONS E XTERNAL S PEAKER If you plan to use an external speaker , choose a speaker with an impedance of 8 Ω . The external speaker jack accepts a 3.5 mm (1/8") mono (2-conductor) plug. We recommend using the SP-50B speaker .
7 1 CONNECTING TO A TNC (E M ARKET M ODELS O NL Y ) To connect an external TNC to the transceiver , use an optional PG-5A cable. The DA T A connector on the rear of the transceiver mates with the 6-pin mini-DIN plug on this cable.

22 6 OPERA TING THROUGH REPEA TERS Repeaters, which are often installed and maintained by radio clubs, are usually located on mountain tops or other elevated locations. They generally operate at higher ERP (Ef fective Radiated Power) than a typical station.
23 6 PROGRAMMING AN OFFSET Y ou must first select an amateur radio repeater downlink frequency as described in “S ELECTING AN O FFSET F REQUENCY ”. S ELECTING AN O FFSET D IRECTION Select whether the transmit frequency will be higher (+) or lower (–) than the receive frequency .
24 6 A CTIV A TING THE T ONE F UNCTION To activate T one, press [F] , [CALL] . •A s you press [F] , [CALL] , the selection cycles as follows: “OFF” ➞ “T ONE” ➞ “CTCSS” ➞ “DCS” ➞ “OFF”. •“ T” appears on the upper part of display , indicating that the T one function is activated.
25 6 AUTOMA TIC REPEA TER OFFSET This function automatically selects an offset direction, according to the frequency on the VHF band. The transceiver is programmed for an offset direction as shown below . T o obtain an up-to-date band plan for repeater offset direction, contact your national Amateur Radio association.
26 6 REVERSE FUNCTION The reverse function exchanges a separate receive and transmission frequency . So, while using a repeater , you can manually check the strength of a signal that you receive directly from the other station. If the station’s signal is strong, both stations should move to a simplex frequency and free up the repeater .
27 6 Note: ◆ Pressing [PTT] causes the “ ” icon to quit blinking. ◆ ASC can be activated while operating in Simplex mode. However , it does not change the T ransmission/Reception frequencies. ◆ ASC does not function while scanning. ◆ Activating ASC while using Reverse switches Reverse OFF .
28 7 MEMOR Y CHANNELS In Memory Channels, you can store frequencies and related data that you frequently use so that you do not need to reprogram that data every time.
29 7 The data listed below can be stored in each Memory Channel: r e t e m a r a P & x e l p m i S r e t a e p e R t i l p S - d d O y c n e u q e r f e v i e c e R s e Y s e Y y c n e u q e r f t.
