- Introduction Thank you for choosing one of the Spectra Precision Lasers from the Trimble family of precision lasers. The HV302/HV302G laser is an easy-to-use tool that allows you to take accurate horizontal/vertical measurements, 90°- and plumb beam transfer. For Your Safety For hazardless and safe operation, read all the user guide instructions. - Use of this product by people other than those trained on this product may result in exposure to hazardous laser light. - Do not remove warning labels from the unit. - The HV302/HV302G is a class 3A/3R laser (<5 mW; 600 - 680 nm / G - 520 nm) IEC 60825-1:2007) - Never look into the laser beam or direct it to the eyes of other people. - Always operate the unit in a way that prevents the beam from getting into people's eyes. - If initial service is required, which results in the removal of the outer protective cover, removal must only be performed by factory-trained personnel. Caution: Use of other than the described user and calibration tools or other procedures may result in exposure to hazardous laser light. Caution: Using different than described at the HV302/HV302G user guide, may result in unsafe operation.

- Installing Batteries Remove the battery door by turning the center screw 90° counterclockwise. Insert batteries (or a rechargeable battery pack) into the housing so that the negative poles are on the bigger battery spiral springs. DO NOT REMOVE RECHARGEABLE BATTERIES FROM THEIR HOLDER AND INSTALL ALKALINE BATTERIES, SEVERE DAMAGE TO UNIT WILL RESULT IF CHARGING IS ATTEMPTED. Install the battery door and tighten it by turning the center screw 90° clockwise. A mechanical switch prevents alkaline batteries from being charged. Only the original rechargeable battery pack allows charging within the unit. Any other rechargeable batteries have to be charged externally.
- Recharging the Batteries Note: The battery LED shows the approximate charge of the batteries. The LED will flash when battery voltage is between 3.8 and 4.0 volts. The LED will be on continuously when battery voltage is less than 3.8 volts. The charger requires approx. 13 hours to charge empty rechargeable batteries. For charging, connect the plug of the charger to the recharge jack of the unit. New or long-time out-of-use rechargeable batteries reach their best performance after being charged and recharged five times. For Indoor applications the charger can be used as a power supply for the GL. Alkaline batteries can be used as a backup. Insert 4 D-cell batteries noting the plus (+) and minus (-) diagrams at the battery door. The batteries should only be charged when the laser is between 50° F and 104° F (10°C to 40°C). Charging at a higher temperature may damage the batteries. Charging at a lower temperature may increase the charge time and decrease the charge capacity, resulting in loss of performance and shortened life expectancy.

- Special Features using the optional RC402N RC402N Features and Functions The remote control mirrors the basic functionality of the laser keypad and offers additional features using the M and E buttons.
- Powering the RC402N 1. Open the battery door using a coin or similar pry device to release the battery door tab on the RC402N. RC402N will be shipped with alkaline batteries Rechargeable batteries can be used optional but need to be charged externally. 2. Insert two AA batteries noting the plus (+) and minus (-) diagrams inside the battery housing. 3. Close the battery door. Push down until it “clicks” into the locked position. Turning On/Off the Radio Remote Control The radio remote control is a hand-held device that allows you to send operational commands to the laser from a remote location. Press the power button to turn on the radio remote control. Note: When the remote control is initially turned on, the standard display (model number and software version) appear for the first 3 seconds, then the RC402N LCD shows the actual laser function. With every button press, the LCD backlight is activated and turns off automatically if no button is pressed for 8 seconds. To turn off the radio remote control, press and hold the power button for 2 seconds. If the RC402N is outside of the operating range or not paired with the transmitter, the LCD shows the model number and software version. Note: 5 minutes after the last button press, the remote control turns off automatically.

Determining the Height of Instrument (HI)
The height of instrument (HI) is the elevation of the laser’s beam.
The HI is determined by adding the grade-rod reading to a benchmark or known elevation.
Set up the laser and place the grade rod on a job-site benchmark (BM) or known elevation.
Slide the receiver up/down the grade rod until it shows an on-grade reading.
Add the grade-rod reading to the benchmark to determine the height of instrument.
Example:
Benchmark = 30.55 m (100.23 ft)
Rod reading = +1.32 m (+4.34 ft)
Height of instrument = 31.87 m (104.57 ft)
Use this HI as a reference for all other elevations.
Vertical Application
Set up the laser on the tripod by using the vertical mounting thread and allow the laser to level in
automatic self-leveling mode.
Push the Manual mode button and rotate the laser until the vertical laser plane aligns with the receiver’s
on-grade position.
Push the manual button again to resume automatic self-leveling mode and use the Left and Right arrow
buttons for fine adjustments.
