IC-706MKIIG Instruction Manual - Repeater Builder

1 Instruction MANUALi706MK GHF/VHF/UHF ALL MODE TRANSCEIVER This device complies with Part 15 of the FCC rules. Operation is subjectto the following two conditions: (1) This device may not cause harmful in-terference, and (2) this device must accept any interference received,including interference that may cause undesired 13:53 Page 1 EXPLICIT DEFINITIONSPRECAUTIONSIMPORTANTRR eeaadd tthhiiss iinnssttrruuccttiioonn mmaannuuaall ccaarreeffuullllyybefore attempting to operate the tthhiiss iinnssttrruuccttiioonn instructionmanual contains important safety and operatinginstructions for the HHIIGGHH VVOOLLTTAAGGEE!! NNEEVVEERR attach an antenna or internal antenna connector dur-ing transmission. This may result in an electrical shockor AC to the [ ] socket on thetransceiver rear panel.

2 This could cause a fire or ruinthe more than 16 V DC, such as a 24 Vbattery, to the [ ] socket on the transceiverrear panel. This could cause a fire or ruin the metal, wire or other objects touch anyinternal part or connectors on the rear panel of thetransceiver. This will cause electric the transceiver to rain, snow orany allow children to play with the using or placing the transceiver in areas withtemperatures below 10 C (+14 F) or above +60 C(+140 F). Be aware that temperatures on a vehicle sdashboard can exceed 80 C, resulting in permanentdamage to the transceiver s front panel if left there forextended placing the transceiver in excessively dustyenvironments or in direct placing the transceiver against walls or puttinganything on top of the transceiver.

3 This will obstructheat mobile operation, DDOO NNOOTT operate the trans-ceiver without running the vehicle s engine. Whentransceiver power is ON and your vehicle s engine isOFF, the vehicle s battery will soon become sure the transceiver power is OFF before start-ing the vehicle. This will avoid possible damage to thetransceiver by ignition voltage maritime mobile operation, keep the transceiv-er and microphone as far away as possible from themagnetic navigation compass to prevent CCAARREEFFUULL!!The heatsink will become hot whenoperating the transceiver continuously for long CCAARREEFFUULL!!If a linear amplifier is connected, setthe transceiver s RF output power to less than the lin-ear amplifier s maximum input level, otherwise, the lin-ear amplifier will be Icom microphones only (supplied or optional).
