HAND-HELD INFRA-RED REMOTE CONTROL
A full function hand-held infra-red remote control is available for the B135 integrated ampli-
fier as an extra-cost option. The hand held remote unit is powered by two “AAA” batteries.
To change the battery remove the bottom cover plate by removing the four Philips screws
on the rear of the remote unit. Ensure that the batteries are correctly oriented and properly
seated in the battery holder.
The BR2remote is a full function remote allowing selection of all sources, volume up or
down (the volume control is a motor-driven design), mute ,left/right balance, power on/off
and discrete code entry. We recommend maintaining a direct line-of-sight between the hand
held remote unit and the front of the B135 to ensure the most efficient operation of the remote
features.
