Basic Operation There are three main modes for the RL101 Head Unit. In addition, there is an OFF mode and a Startup mode. When the unit is powered, there is a 30 second (Startup) countdown during which some system values are displayed before going into the Normal Operating mode.
1. Normal Operation The RL101 Head unit monitors the gas level. If the gas level is greater than or equal to the background setting, the unit will send a message every 5 seconds; if less than the background setting, the unit will send a message every 5 minutes.

3. Calibration Use the Up and Down buttons to adjust the reading to match the value Press Menu button or of the calibration gas use reed switch twice to enter “CAL” mode To place the Rl101 into CAL Mode press the MENU button twice "CAL" will flash on the display. The RL101 Head unit monitors the gas level but does not send messages to the monitor when in CALIBRATION mode.
(This mode is new to revisions 2.0 or greater). If the RL101 sensor head is in the wrong setting of 784, use the up or down buttons to change back to “Red”. ** if the RL101 sensor head is in 784 it will not communicate to the Redline Monitor** 8. Revision This mode shows the revision of the software that is being used in the RL101 Head unit.

10. Radio Signal Strength Input To get to this mode press the TEST button twice and the MENU button twice "rIn" will then flash in the display. This mode allows the Head unit and Monitor to exchange messages (this mode is disabled when in the 784 mode since the 784 does not resend any messages).
The Rl101 Head may be mounted 18 to 24 inches above the ground with the sensor housing pointed down towards the ground. For best signal strength position the glass window in line of sight of the Redline Monitor, also make sure there are no metal/nonmetal obstructions so signal will not be blocked. MAINTENANCE Redline Instruments recommends you check battery voltage every 90 days and Calibration of the head every 30 days.
