Tool Information

The CMHT77638 tool is a Class 2 laser product that is used to measure distances up to 65ft, area, volume, or the height of a tall object.

User Safety

WARNING:

Carefully read the Safety Instructions and Product Manual before using this product. The person responsible for the product must ensure that all users understand and adhere to these instructions.

WARNING:

The following label information is placed on your laser tool to inform you of the laser class for your convenience and safety.

WARNING:

If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired.

The CMHT77638 tool emits a visible laser beam, as shown in Figure A. The laser beam emitted is Laser Class 2 per IEC 60825-1 and complies with 21 CFR 1040.10 and 1040.11 except for deviations pursuant to Laser Notice No. 50, dated June 24, 2007.

WARNING:

While the laser tool is in operation, be careful not to expose your eyes to the emitting laser beam (red light source). Exposure to a laser beam for an extended time period may be hazardous to your eyes. Do not look into the beam with optical aids.

WARNING:

To reduce the risk of injury, user must read the Product User manual and the Safety manual.

FCC Compliance

This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.

FCC Statement

This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and the receiver.
• Connect the equipment into an outlet on a different circuit (not the circuit to which the receiver is connected).
• Consult the dealer or an experienced radio/TV technician for help.

Canada, Industry Canada (IC) Notices

Class B digital circuitry of this device complies with Canadian ICES-003. This device complies with Industry Canada license-exempt RSS standard(s). Operation is subject to the following two conditions: (1) this device may not cause interference, and (2) this device must accept any interference, including interference that may cause undesired operation of the device. Under Industry Canada regulations, the radio transmitter(s) in this device may only operate using an antenna of a type and maximum (or lesser) gain approved for the transmitter by Industry Canada. To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for successful communication.

Setup

Attaching the Wrist Strap

1. While facing the front of the tool, insert the thin end of the wrist strap through one of the holes in the bottom of the tool (Figure A 5).
2. Push the thin end of the wrist strap until it goes through the other hole.
3. Separate the two wires, which make up the thin end of the wrist strap, to form a loop.
4. Insert the thick end of the wrist strap all the way through the loop in the thin end, so the wrist strap is securely fastened to the tool (Figure C).

Charging the Battery

Fully charge the battery before initial use and whenever the tool has not been used for 6 months or longer.

1. Locate the port cover on the side of the tool (Figure D 1).
2. Using your finger, gently pull the port cover up (Figure D 1).
3. Insert the small end of the USB Recharge Cable into the port on the side of the tool, making sure to insert the flat side of the cable into the flat side of the port (Figure D 2).

4. Insert the USB end of the cable into a USB port in a computer or USB power outlet (Figure D 3).

5. Wait approximately 2.5 hours for the battery to fully charge and then disconnect the USB Recharge Cable.

When the tool is ON, the battery level appears in the display window (Figure F 1).

Measuring the Height of a Tall Object

If you need to measure the height of a tall object (e.g., a tall building), you can calculate the height based on the distances from the same point to 2 or 3 points on the object. The tool will use the Pythagorean Theorem (C^2 = A^2 + B^2) to calculate the height.

Distances to 2 Points

You can use the distance to two points on a tall object (Double Indirect Height) to determine its height (Figure ①①).

5. Aim the laser at the highest point of the building or object (Figure 12).
6. Press measure the distance.
7. From the same point, aim the laser straight ahead toward the lowest point of the building or object (Figure 1 3).
8. Press measure the distance.

E

1. On the bottom line of the screen, view the height of the building or object.

Distances to 3 Points

You can use the distance to three points on a tall object to determine its height (Figure ①).
