P7170IP System Radio.

8.1.1 Buttons and Knobs

This section describes the primary function of the button and knob controls. Other functions associated
with these controls are detailed in later sections.
Applies power to and adjusts the receiver’s volume. Rotating the control
clockwise applies power to the radio. A single alert tone (if enabled through
programming) indicates the radio is operational.
Rotating the control clockwise increases the volume level. Minimum
volume levels may be programmed into the radio to prevent missed calls
due to a low volume setting. While adjusting the volume the display will
momentarily indicate the volume level (i.e. VOL=31). The volume range is
from a minimum programmed level of zero (displayed as OFF in the
display) up to 31, which is the loudest level.
POWER ON-OFF
VOLUME KNOB
CONTROL KNOB Selects systems or group/channels (depending on programming). This is a
16-position rotary knob.
Note: A mechanical stop, which can limit the positions accessed, is shipped
with the radio but must be installed. To install the mechanical stop, remove
the channel knob, loosen the set screw on the channel knob metal base
(using a 1.27mm hex wrench), and remove the channel knob metal base.
Replace the 16 channel ring with the channel stop ring located at the desired
channel. Reinstall the channel knob metal base, tighten the set screw, and
reinstall the channel knob.
