Battery Installation

This device is designed for easy set up. The following steps are required to be done in the proper sequence. Please

insert batteries for the receiving unit before the remote sensor

1. Press and slide to open the battery cover at the back of the unit. Insert 2 AA batteries according to the polarity

marks inside the battery compartment

2. Close the battery cover

3. Once you have properly installed the batteries, the LCD display will show the full display for 3 seconds and enter

the normal mode after the beep sound. The time will default to 0:00 and calendar to January 1. The alarm will

default to 0:00, the weather icon will default to partly sunny. The temperature scale will default to °C. The time

Wireless Remote Sensor Registration Procedure

1. Lift off the bracket stand of the remote sensor by sliding the bracket

2. Use a Phillips head screwdriver to remove the screws on the battery cover

3. Insert 2 AAA batteries according to the polarity markings on the battery compartment

4. Once the batteries are inserted, the sensor will start transmitting temperature readings for 3 minutes

5. The receiving unit will display remote channel 1 and the temperature reading

6. After registration is completed for sensor 1, put the rubber seal into the cover groove, close the battery cover,
tighten the screws, and slide on the bracket stand. Follow the same procedure if installing additional remote
sensors.

NOTE:

After you have placed the sensor in the remote location, observe the receiving unit channel display for that sensor
after 35 minutes. If the (--) dash icon is flashing for channel one, the signal has been lost, try rotating the sensor in
45° steps, wait for at least 3 minutes after each position change. Observe the receiving unit channel display on each
position to determine that the remote temperature display has been restored, if not, move the remote sensor closer
to the receiving unit or reposition both the receiving unit and the remote sensor until reception is observed.

Installation of Remote Sensors

Locating remote sensor in a clear open area can attain a maximum of 30-meter (100ft) transmission distance. Actual
transmission distance can be reduced by interference from buildings, obstructions, or a screen between the remote
sensors and the receiving unit. The remote sensor(s) have been designed to accommodate a variety of mounting
options. The remote sensor(s) can be hung on a flat wall by means of a wood screw. You can also use the stand on
a desired horizontal surface.

Battery Replacement

A low battery icon will appear on the display of the receiving unit when the batteries of the receiving unit and remote
sensor(s) need to be replaced. When replacing batteries always use new batteries as specified. Do not mix old and
new batteries as the old ones may leak.

Troubleshooting for lost signals

If without obvious reason the display for a particular channel suddenly goes (--) dash, check:

1. That the remote unit of that channel is still in place

2. That the batteries of both the receiving and remote unit are still good. Replace as necessary.

3. That the transmission is within range and path is clear of obstacles and interference. Shorten the distance when
necessary

4. Signals from other household devices, such as doorbell, home security system, and entry controls, which may
interfere with those of this product and cause reception failure. This is normal and does not affect the general
performance of the product. The transmission and reception of temperature readings will resume once the
interference ceases.

Precautions

1. Do not clean the units with abrasive or corrosive compounds. They may scratch the plastic parts and corrode the
electronic circuits

2. Do not subject the unit to extensive force, shock, dust, temperature or humidity, which may result in
malfunctioning, shorter electronic life span, damaged batteries, and distorted parts

3. Do not tamper with these units’ internal components. Doing so will invalidate the warranty of the unit and may
cause unnecessary damage

4. Do not subject the unit to excessive exposure to direct sunlight. Although the remote sensor has splash proof
design, never submerse it in water or expose it to heavy rain.

5. Always read the user manual thoroughly before operating the unit

6. This device could be sensitive to electrostatic discharge. If electrostatic discharge or malfunctioning occurs,

please reset the unit
