About the LEIT RC2 2-way Remote Control Handset

Thank you for purchasing DIG’s LEIT RC2 Remote Control Handset. This manual will
describe how to use the LEIT RC2 handset and get the LEIT RC2 handset up and running
quickly. After reading this manual and have after you familiarized yourself with the basic
functionality of this device, the manual can be used as a reference for less common tasks
in the future.

The LEIT RC2 Series Remote Control Handset is an advanced wireless device that
communicates with up to 99 LEIT2 ambient light (solar) powered irrigation controllers. The
RC2 has a large LCD display and sophisticated, intuitive icon base software to
communicate with a LEIT2 controller. A compact photovoltaic module powers the LEIT2
controller to harnesses light energy, generating electricity to power the controller day and
night in any kind of weather. The handset and the controllers have an operating range via a
two-way radio of up to 350 ft (100 m), line of sight.

The LEIT2 controller requires daily exposure to light levels at a minimum of 3000 lux,
which is equivalent to daylight around 7-8 AM on a cloudy day. On very cloudy days the
controller requires more time to charge up and to operate with the radio.

IMPORTANT:
daylight hours when there is sufficient light energy. Longer bright light days will enable the radio to operate
automatically over longer part of day.

Communication between the LEIT RC2 and the LEIT 2 controllers are automatically limited to

4. Battery Charge Outlets and Recharging the Battery

The LEIT RC2 contains a cell battery pack that is rechargeable using the AC/DC wall mounting
charger 120 or 220 VAC/60 h2, 12 VDC @150 mA. To charge the LEIT RC 2 Handset, plug the
wall mount charger into the wall and connect the power connector to the side of the LEIT RC 2
handset for approximately 8 hours for an initial charge before using it. Then charge it daily for a few
hours as needed. If the handset is off, you will see a charging icon and a battery appear. The
battery repeats a filling action, indicating that the battery is charging. Once the battery is charged, it
will stop the filling motion, and the wording CHARGED will appear.

A car charger model 30-851 can

be purchased if needed.
