MAINTENANCE 11 ■ Opening the transceiver's case Follow the case opening procedures shown here when you want to replace the clock backup battery or internal fuse. CAUTION: Turn the power OFF and disconnect the DC power cable from the transceiver before performing any work on the transceiver. Otherwise, there is danger of electric shock and/or equipment damage. q R emove the two screws from the carrying handleand remove the handle from the transceiver. w R emove the 6 screws from the top of the transceiver and the 4 screws from the sides, then lift up the top cover. e Turn the transceiver upside-down. CAUTION: NEVER HOLD THE MAIN DIAL OR ANY OTHER KNOBS when the transceiver is being turned upside down. This may damage the transceiver. r R emove 6 screws from the bottom, then lift up the bottom cover. ✔ About the leg pads To detach the leg pads from the right side panel of the top/bottom cover, push them from the inner side of each cover after steps q to r as above. Carrying handle ■ Clock backup battery replacement The IC-7600 has a lithium backup battery (CR2032) inside for clock and timer functions. The usual life of the backup battery is approximately 2 years. When the backup battery is discharged, the transceiver transmits and receives normally but cannot retain the current time. CAUTION: Turn the power OFF and disconnect the DC power cable from the transceiver before removing the transceiver's cover. q Remove the bottom cover as shown above. w R eplace the clock backup battery, located on the front panel as illustrated at right. • Make sure the battery polarity is correct. e Return the bottom cover to the original position. r Set the date and time in time set mode.
