- if one of the yellow (G1, G2, IP) warning LEDs is illuminated along with the "F" LED, a current limit

has been exceeded; drive power must be reduced or retuning is necessary;

- if the last red LED of the reflected-power bar-graph is illuminated together with the "F" LED, the

reflected-power limit has been exceeded; the drive must be reduced or the antenna VSWR must be

improved.

- if all three LEDs of the TRI are flashing simultaneously together with the "F" LED, the tuning is not

adjusted correctly; most likely the antenna impedance has changed and retuning is required.

Fault information normally remains on the display for several seconds while the amplifier is in the standby

mode. The auto-operate function will attempt to return the amplifier to the operate mode automatically.

If the protection trips repeatedly, the user must attend to the cause of the trip, which is typically too

much drive or antenna mismatch.

If all LEDs in the bar-graph area are flashing simultaneously, you must immediately

switch off the amplifier to avoid damage.

5. MAINTENANCE

If no indicator glows upon switching the amplifier on, the main fuse(s) may have blown. See Section

5-2.

5-1. Cleaning

Do not use solvents for cleaning as they may be dangerous to you and damage

amplifier surfaces and plastic components.

Do not open the amplifier. Cleaning the amplifier outer surface may be safely accomplished by using a

piece of soft cotton cloth lightly moistened with clean water.

5-2. Fuse Replacement

If your amplifier is only fitted with one line (mains) fuse, it is suitable for the

European Community ONLY. Your dealer will check that your amplifier is

correctly fused before it is shipped to you, based upon your indicated location.

Customers should check with a qualified electrician if the amplifier is to be

used outside the country in which it was purchased.

For 120 V ac operation, the fuses should be rated at 10 A; for 240 V ac operation,

the fuses should be rated at 6.3 A. If it is necessary to replace the line (mains) fuses,

use only those that are permitted under local safety codes.
