2 INSTALLATION AND CONNECTIONS Selecting a location Heat dissipation Select a location for the transceiver that allows adequate air circulation, free from extreme heat, cold or vibrations, and other electromagnetic sources. The transceiver has a stand for desktop use. ••DO NOT place the transceiver against walls or put anything on top of the transceiver. This may block 1 airflow and overheat the transceiver. ••NEVER install the transceiver in a place without 2 adequate ventilation. Heat dissipation may be reduced, and the transceiver may be damaged. 3 ••DO NOT touch the transceiver after transmitting continuously for long periods of time. The transceiver 4 may become hot. 5 Grounding 6 Stand To prevent electrical shock, television interference (TVI), broadcast 7 interference (BCI) and other problems, ground the transceiver 8 using the ground terminal [GND] on the rear panel. 9 CAUTION: NEVER carry the transceiver by holding the For best results, connect a heavy 10 stand, dials, controls and so on. This may damage them. gauge wire or strap to a long ground rod. Make the distance between the 11 [GND] terminal and ground as short as possible. 12 13 RWARNING! NEVER connect the [GND] terminal 14 to a gas or electric pipe, since the connection could cause an explosion or electric shock. 15 16 Front panel connection 17 [MIC] (Microphone) connector 18 19 SM-50 (Option) SM-30 (Option) HM-219 (Supplied) Using an External Keypad You can control the CW memory keyer, Voice memory or RTTY memory keyer transmission from an external keypad by connecting the control circuit to the [MIC] connector. Set the "External Keypad" to ON on the CONNECTORS screen to use the external keypad.
