OPERATION 

 

2.1.

 

  FRONT PANEL 

 

 

 
The front panel is divided into two parts: One for tuning and band switching (left) and another 
for the visualization.(right) 
 
The tuning part consists of a 

TUNE

LOAD

 and 

BAND

 knob.  

In  the  visualization  part  there  are  three  buttons: 

STBY/OPR

DOWN 

and 

UP 

for 

standby/operate switching and display control. Besides, there are three LEDs: a red TX (lights 
up  when  transmitting),  a  green  OPR  (lights  up  when  in  operate  mode)  and  a  yellow  ATT 
(lights up when the   built-in attenuator is switched on). 
 
The 

POWER

 switch is in the lower right corner of the front panel. 

 
 

2.2.

 

POWER ON 

 
To start up the amplifier, use the 

LINE SWITCH 

on the back panel of the amplifier. Now you 

will see the following message coming up on the LCD display at the front panel: 
 

 

 

Now you can switch on the ALPIN 100 with the 

POWER SWITCH

 on the front panel. After 

this, it will need another 2:30 min for heating up the tube. The LCD display will inform you 
about the remaining time until the amplifier has reached 

STANDBY MODE

 with the following 

two messages. They will alternate with a 5-second- cycle.
