DISPLAY MESSAGES

HHH – Three Hs flashing indicate the relative humidity being measured is above the

range of the unit.

LLL – Three Ls flashing indicate the relative humidity being measured is below the

range of the unit.

- - – Two dashes indicate the temperature, although still displayed, is above the range

of the unit.

MOUNTING THE UNIT

1. To allow for different mounting positions, the white unit holder fits securely over the top or bottom of the unit.

2. Select the position and location where the unit will be mounted.

3. Make sure the surface of the location is clean and smooth.

4. Attach the unit to the selected location by removing the paper covering from the adhesive tape on the back of the unit holder and pressing the unit firmly in place.

5. The unit can be more permanently mounted by utilizing the two small screw holes on the unit holder. (Screws are not included.)

BENCH STAND

1. The bench stand is part of the BATTERY COMPARTMENT DOOR.

2. Locate the small rectangular opening at the bottom of the BATTERY COMPARTMENT DOOR.

3. Insert paper clip into opening and gently turn ⅛” in either direction. Stand will flip open.

4. To close, snap the stand closed.

ALL OPERATIONAL DIFFICULTIES

If this unit does not function properly for any reason, please replace the batteries with two new AAA alkaline batteries. (See “Battery Replacement” below.) Low battery power can occasionally cause any number of “apparent” operational difficulties. Replacing the batteries with fresh ones will solve most difficulties. Equivalent battery replacements are any AAA alkaline batteries. Replacement battery Cat. No. 1105.

BATTERY REPLACEMENT

1. To open battery compartment, slide BATTERY COMPARTMENT DOOR on the back of unit in direction of arrow.

2. Remove depleted batteries. Insert two fresh AAA alkaline batteries in appropriate positions to agree with the polarity symbols (+ and -) in the battery compartment.
