Inventory of contents:

1． one indoor station
2． one remote sensor
3． Instruction Manual

Function:

1． Indoor temperature

2. Outdoor temperature
3 Min/Max record of temperature

4. Switch from ˚C to ˚F for temperature unit

5. Quartz time, calendar date.

6. Flip out desk stand or wall mount.

Quick Setup

Hint：Use good quality Alkaline batteries and avoid using rechargeable。

1. Have the indoor temperature station and remote temperature sen sor 3
to 5 feet apart.

2. Place the batteries into the indoor temperature station first. All LCD
segment will be turned on for 4 seconds, then the Outdoor Reception
Signal Icon displayed, indicating that receiver is trying to find the
remote sensor. Then place the batteries into the remote temperature
sensor, transmitter will send out a temperature reading value first,
after this the red signal light will be turned on for 8 seconds. Within
one minute, outdoor temperature data will be displayed indicating that
receiver has synchronized with the transmitter. After both indoor and
outdoor temperatures are displayed for 15 minute s y ou ca n place y our
remote sensor outdoors and set your time.

3. If a key is pressed before the weather station receives the
temperature signal, it will take 10 minutes before the receiver
re-synchronizes with the outdoor sen s or again. If a reset is needed for
receiver or transmitter, pull out the batteries and wait 10 seconds
before re-insert the battery to make a proper reset.

To wall mount:

1. Fix a screw (not supplied) into the desired wall, leaving the head
extended out by about 5mm.

2. Hang the Temperatures Station onto the screw. Remember to ensure
that it locks into place before releasing.

How to fix outdoor sensor

Note: To achieve a true temperature reading, avoid mounting in direct
sunlight. We recommend that you mount the remote sensor on an outside
North-facing wall; obstacles such as w alls, con crete, and la rge met al o bject s
will reduce the range.

Maintenance and Care

1. Extreme temperatures, vibration, and shock should be avoided to
prevent damage to the units.

2. Clean displays and units with a soft, damp cloth. Do not use solvents
or scouring agents; they may mark the displays and casing.

3. Do not submerge in water.

4. Do not subject the units to unnecessary heat or cold by placing them
in the oven or freezer.

5. Opening the casings invalidates the warranty. Do not try to repair the
unit..

The remote temperature sensor should be placed in a dry, shaded area.
The thermometer sensor has a range of 150 feet. Keep in mind that the 150
feet is in free open air with no obstructions and that radio waves DO NOT
curve around objects. Actual transmission range will vary depending on
what is in the path of the signal. Each obstruction (roof, walls, ceilings, thick
trees, etc.) will effectively cut signal range in half.
