Universal Remote Control URC-300 ユーザーズマニュアル

In most home entertainment systems, the sound 
volume is only controlled by one device. In some 
systems, it is the TV speakers that make the sound, 
so you would use the TV device on the Customizer to 
raise and lower the volume. In another system, it might 
be a surround sound receiver and speakers that control 
the sound, so you would use the Customizer’s AUDIO
device to adjust the volume. Constantly switching the
Customizer to TV or AUDIO to adjust the volume is
inconvenient in daily life.

You can use Punch Through to set the Customizer’s 
volume buttons to always control the sound in your 
system. That way when the Customizer is set to VCR  
or DVD, the volume up, down and mute buttons will 
work perfectly without switching back to AUDIO or 
TV. Here’s how:

Press and hold both the MAIN and ENT (Enter) 
buttons for three seconds. The top of the display

shows that you are in SETUP mode now.

Note: You have 30 seconds for each step, otherwise the
Customizer will time out automatically. 

From the Setup menu, press the PUNCH button.

Press the VOL button. The display confirms by
displaying “VOL” at the top of the screen. This sets
up the group of three buttons (Volume Up, Volume
Down and Mute) in one action!
