for the lowest possible VSWR. After taking the reading, return the switch to the SET
position.
2. DIMMER SWITCH |
For optimum visual comfort, the meter lamps and frequency display LEDs are dimmed
and brightened, depending on the brightness or darkness of the surrounding light, by use
of the DIMMER SWITCH.
When the DIMMER SWITCH is turned ON (down), the meter lamps and the frequency
display LEDs are dimmed.
FOR SATELLITE COMMUNICATION USE
At present there are two active satellites for amateur radio use, AMSAT OSCAR 7 was
launched in November, 1974 and AMSAT OSCAR 8 was launched in March, 1978. Satellite
communications can be made by using an IC-211 for receiving/transmitting and 1С-402
(70 centimeter SSB/CW transceiver) for transmitting/receiving in Mode B and Mode J, and
an IC-211 for transmitting and IC-701 (HF SSB/CW/RTTY transceiver) for receiving in
Mode A.
NOTE: FM mode is prohibited for these satellite communications.
For frequency information refer to the chart below. Further information on communicating
through satellites can be found in various amateur radio books and periodicals.

CONNECTION OF ACCESSORY SOCKET
Various adapters can be used through terminals in this SOCKET for frequency control input,
modulation output, receiver output, T/R change-over control and so on. The table on the
next page shows terminal connections of this connector. Care should be taken nót to apply
voltages other than —0.5V to +5V to terminals between No. 15 and No. 24 as they are
connected with the C-MOS IC (LSI).
