Acom ACOM1010 - Changing Operate and Standby Modes; RTTY Mode; Antenna Change

CAUTION
To avoid damage not covered under warranty, do not change the antenna output
during a transmission, i.e., never press the
A1-A2
button when transmitting.
NOTE
When you intend to have a short operating break, it is better to place the amplifier
in the standby mode rather than turning it off. Tube life is shortened by repeatedly
turning it on and off.
After the warm-up period is complete, the
OPER
LED stops flashing and remains illuminated green.

the amplifier will remain ready to operate, even automatically returning from standby after a high-drive
protection trip. That is, after a protection trip, e.g., from an overdrive event, the amplifier will normally
shift to the
STBY
mode for several seconds, but it will automatically return to the

To avoid damage not covered under warranty, do not change modes during
transmission. That is, do not change to or from
RTTY

transmitting.
4-4. Antenna change
By pressing the
A1-A2
button, the amplifier output is switched between the two corresponding antenna
outputs,
ANT1
and
ANT2
. The lights above the button indicate the current antenna selection.
