The Viking model SA-IR is a three button infrared remote control for use with the Viking Model SA-1S and SA-1H (pending) self amplified
paging speakers. Aim the infrared transmitter at the speaker and press the buttons. The up/down buttons allow users to set the appropriate volume level for each room. The speaker provides an audible “beep” feedback tone to let the user gauge the volume level even when there’s no background music (or page) playing at the time.
