Testing Mode

Once on, when the power button is 
pressed for a long time, the RAM-L enters 
a mode for system testing. This special 
mode is intended for system debugging 
and testing. When the RAM-L is turned 
off, the special mode is reset. Upon 
restarting the RAM-L the current standard 
settings stored by GLM software are 
restored. 

Test mode selection blinks the power 

button light (see Table 2). A special mode 
is activated by a long press on the power 
button. In a special mode the power 
button light remains on but blinks off 
1-4 times indicating the mode currently 
selected. 

The testing modes are not intended for 

continued operation. Use GLM software to 
set up permanent settings for 1238AC.  

Safety Considerations

The 1238AC has been designed in 
accordance with international safety 
standards. To ensure continued safe 

operation and to maintain the monitor under 
safe operating conditions, the following 
warnings and precautions must be observed:

1.  Servicing and adjustment must only 

be performed by qualified service 
personnel. The monitor enclosure or 
the amplifier enclosure must not be 
opened.

2.  Do not use this product with a 

mains cable with no protective earth 
conductor, or a mains connection 
without the protective earth contact, 
as this may lead to personal injury.

3.  To prevent fire or electric shock, 

do not expose the unit to water or 
moisture. 

4.  Do not place any objects filled with 

liquid, such as vases or water pipes 
on the amplifier or near it. 

5.  Note that the amplifier is not 

completely disconnected from the AC 
mains service unless the mains power 
cord is removed from the amplifier or 
the mains outlet.

6.  Free flow of air around the amplifier 

is necessary to maintain sufficient 
cooling. Do not obstruct airflow 
around the amplifier.

WARNING! 

The Genelec 1238AC monitor is capable of 
producing sound pressure levels in excess 
of 85 dB, which may cause permanent 
hearing damage.

Maintenance

No user serviceable parts are to be found 
within the monitor enclosure or the RAM-L 
amplifier unit. Any maintenance or repair of 
the monitor should only be undertaken by 
qualified service personnel.
