BASIC OPERATIONS ■ When first applying power (CPU resetting) Before first applying power, make sure all connections required for your system are complete by referring to Section 2. Then, reset the transceiver using the follow- ing procedure. Resetting CLEARS all programmed contents in memory channels and returns programmed values in set mode to default values.
Page 39: Main/Sub Band Selection
BASIC OPERATIONS ■ Main/Sub band selection The IC-7800 has 2 identical receivers, main and sub. The main band is displayed on the left hand side, and the sub band is displayed on the right hand side of the LCD. Some functions can only be applied to the selected band and transmission occurs on the main band (except during split frequency operation).
Page 40: Selecting An Operating Band
BASIC OPERATIONS ■ Selecting an operating band The triple band stacking register provides 3 memories Band keys for each band key, storing frequency and mode infor- mation. If a band key is pushed once, the frequency and op- erating mode last used are called up. When the key is pushed again, another stored frequency and operating mode are called up.
