5.2.4 How to enable Local mode and RF output
Check current mode setting and enable
Local mode (if not already enabled)
following menu path
Fnc ⇒ Loc ⇒ Local(figure5.2-menu4):ifleftdisabled,
the machine will not accept the next commands.
Check current
RF output setting and enable output (if not already enabled) following
menu path
Fnc ⇒ Pwr ⇒ ON(figure5.2-menu4)
Check output power level and set to maximum level (if not already set to maximum)
from the Power Setup Menu, which you can call up by pressing these keys in the
order:
ESC (opens Default Menu) ⇒ ENTER (hold down for 2 seconds) ⇒ SET
⇒
usekeytosetbartomaximumlimit(figure5.2-menu2).

output power. Never exceed 1100W output power.
Note : Normally, drive power should not exceed 20W (typically 18W): higher drive
power requirements are a symptom of abnormal operation.

5.2.6 RF output power level control
IMPORTANT: The amplifier incorporates Automatic Gain Control and output
power is modulated based on the power level set by the user and actual operating
conditions, such as temperature, reflected power and other parameters. Drive
power must be kept steady at maximum output power capacity. Please read section
5.3 for more details of RF power modulation.
