POWER SOURCE

RL-H5A (Using the rechargeable battery)
Be sure to charge the battery fully before using it for the first time or after not using it for long periods.
Charging

1. Remove the DB-79A battery holder by turning battery holder knob to “OPEN” side.

2. Connect the AD-17B/C/D/E into the charge port of the battery pack BT-79Q.

3. Plug the AD-17B/C/D/E into the wall outlet.
   When charging starts, the LED is solid red. The LED is off when charging finished.

4. Unplug the AD-17B/C/D/E from the battery pack BT-79Q and disconnect the AD- 17B/C/D/E power plug from the wall outlet.

The LED of BT-79Q indicates the charging status:

automatically.
Let the battery pack fall within its designated charging temperature range (10 to 40°C), unplug the AD-17B/C/D/E from the battery pack and then check the LED status. Solid red LED indicates charging has started again. Slow blinking red LED indicates the Ni-MH battery is still out of the charging temperature range. Wait for a while, unplug the AD-17B/C/D/E and then check the LED again.
The instrument has a protection feature which works when the batteries are under a high or low temperature state. In such a case,  charging will stop automatically to protect nickel hydride batteries.
Red blinking quickly:| The battery is not charged properly. Please contact your local dealer.

• The charger will become rather hot during use. This is normal.
• Do not use batteries other than those designated.
• For longer battery life, conform to the suggested charging time to the extent possible.
• Be sure to charge stored battery source every 3 or 6 months and store in a place at 30°C or below. If you allow the battery to become completely discharged, it will have an effect on future charging.
• Batteries generate power using a chemical reaction and as a result have a limited lifetime. Even when in storage and not used for long periods, battery capacity deteriorates with the passage of time. This may result in the operating time of the battery shortening despite having been charged correctly. In this event, a new battery is required.

Installing

1. Insert the battery pack BT-79Q into the DB-79A battery holder.
2. Install the battery holder. Tighten the battery cover knob to “LOCK” side.
   • It is possible to remove the battery pack BT-79Q from the DB-79A battery holder and use the dry cell batteries.
   Grasp the specified place on the battery holder, which is shown on the right, and remove the battery pack.

Height Alert Function
When the instrument system detects a shock, this function informs the operator of it.

• When the instrument’s installation status (height) is sharply changed by the contact of the operator or the like, this function stops selfleveling to keep the operation accuracy and informs the operator of the situation. The three lamps blink at the same time as shown at the right.
• After 1 minute has passed since the self-leveling function was activated and the laser beam was emitted, this function works.
• The height alert function does not work in the “Manual” mode.

The three lamps blink at the same time and the rotary head rotates at low speed.
[How to reset]

1. Turn off the power switch.
2. Check whether the instrument is installed correctly.
3. Turn on the power switch. Self-leveling starts again. After self-leveling is finished, the laser beam is emitted.
4. Make sure that the laser beam is set at the correct height. Then, restart the operation.

Aligning Direction of Slope
It is possible to set slope only in the X axis direction (refer to “CHECKS AND ADJUSTMENTS”).
[1. Installation of the instrument]
When using the laser to set the slope, the laser must be properly aligned so the slope axis of the laser beam is parallel to the desired direction of slope.
The sight on top of the instrument is calibrated to the slope axis of the laser beam. Follow the steps below to align the laser to the desired direction of slope:

1. Establish a target line parallel to desired direction of slope.
2. Set up the laser over this line (drop a plumb bob from the tripod mounting screw).
3. Rough align the instrument to the direction of slope. Make sure it is properly oriented for the slope to be set.
4. Using the sight, position the instrument so the sight is centered on the target. (see illustration below)

[2. Setting slope]

Operating procedure (Setting slope)| Key operation| Lamp display (Refer to the right illustration)

5 Press Power switch OFF to cancel the slope setting.| Power switch| All lamps are OFF.

• After setting the slope, the self-leveling does not function in the X axis direction.
Lamp Position

How to set the slope before the power is OFF again

1. To set the slope before the power is OFF again, turn on the Power switch as pressing either right or left of the Slope keys. The slope is kept and you can adjust the slope in the same way as Step 4. (When the Power switch is ON without the Slope key pressed, the laser beam will return to level.)

• When you set the “Manual” mode to ON after setting the slope, the beam is fixed at the set slope position. At this time the Slope key does not function. For information about Manual mode ON/OFF, refer to “NOMENCLATURE AND FUNCTIONS”.
• Check the beam often during slope use for slope accuracy. Check instrument calibration periodically.

CHECKS AND ADJUSTMENTS

4. Using the level sensor, mark the on-grade height of laser beam on a wall.
5. Rotate the instrument 180 degrees to face Y2 side toward a wall.
6. In the same way as step 4, mark the on-grade height of laser beam on a wall.
7. Press the slope key to make adjustment so that the laser beam height may be at the center between the positions of Step 4 and Step 6.
8. Press the height alert OFF key to memorize the new laser beam calibration. The height alert OFF lamp will blink. Power will shut off automatically when the calibration memorization is complete. The Y axis adjustment is completed now.

If the height alert OFF lamp blinks quickly and the power is not automatically turned off when pressing the height alert OFF key to memorize the height, the height exceeds the adjustment range. Please contact your local dealer.
To discontinue calibration the instrument, press the Power switch.
Checking cone error

Perform the following check after completing horizontal calibration procedure.
[Checking]

1. Set up the laser centered between two walls approximately 40m (131ft) apart. Orient the instrument so one axis, either X or Y, is facing the walls.
2. Locate and mark the position of the rotating laser beam on both walls using the level sensor.
3. Turn off the instrument and move the instrument closer to wall A (1m to 2m /3 ft to 6 ft). Do not change the axis orientation of the instrument. Turn the instrument on.
4. Again locate and mark the position of the rotating laser beam on both walls using the level sensor.
5. Measure the distance between the first and second marks on each wall. If the difference between each set of marks is less than 4mm (5/32 of an inch), no error exists.

• If the difference value is greater than 4mm (5/32 inch), contact your local dealer.
