2. PRECAUTIONS
Precautions concerning water and dust resistance
DL conforms to IP54 specifications for waterproofing and dust resistance when the battery cover,
External interface hatch, and Multi Port cap is closed.
• Make sure that moisture or dust particles do not come in contact with the terminal or connectors.
Operating the instrument with moisture or dust on the terminal or connectors may cause damage to
the instrument.
• Be sure to correctly attach the connector cap to protect the DL from moisture and dust particles
when the connector is not in use.
• Make sure that the inside of the carrying case and the instrument are dry before closing the case.
If moisture is trapped inside the case, it may cause the instrument to rust.
The Lithium Battery
The lithium battery is used to maintain the DL Calendar & Clock function. It can back up data for
approximately 5 years of normal use and storage (Temperature = 20°, humidity = about 50%), but its
lifetime may be shorter depending on circumstances. When the voltage of the lithium battery has
decreased, or the battery itself is depleted the date/time may not be displayed correctly and an error
message "The battery for the clock function needs to be replaced." will be displayed.
For details on replacing lithium batteries contact your local dealer.
Backing up data
Data should be backed up (transferred to an external device etc.) on a regular basis to prevent data
loss.
Other precautions
• Never place the instrument directly on the ground. Sand or dust may cause damage to the screw
holes or the centering screw on the base plate.
• Protect the instrument from heavy shocks or vibration.
• Protect the instrument from rain or drizzle with an umbrella or waterproof cover.
• When the operator leaves the instrument attached to the tripod, the vinyl cover should be placed on
the instrument.
• Never carry the instrument on the tripod to another site.
• Turn the power off before removing the battery.
• Remove the battery before placing the DL in its case.
• Make sure that the instrument and the protective lining of the carrying case are dry before closing
the case. The case is hermetically sealed and if moisture is trapped inside, the instrument could
rust.
• Consult your local dealer before using the instrument under special conditions such as long periods
of continuous use or high levels of humidity. In general, special conditions are treated as being
outside the scope of the product warranty.
Maintenance
• Wipe off moisture completely if the instrument gets wet during survey work.
• Always clean the instrument before returning it to the case. The lens requires special care. First,
dust it off with the lens brush to remove tiny particles. Then, after providing a little condensation by
breathing on the lens, wipe it with the wiping cloth.

country where the instrument is being used. Contact your local dealer in advance.
Bluetooth
Wireless Technology
"26. REGULATIONS"
• TOPCON CORPORATION is not liable for the content of any transmission nor any content related
thereto. When communicating important data, run tests beforehand to ascertain that communication
is operating normally.
• Do not divulge the content of any transmission to any third party.
Radio interference when using Bluetooth technology
Bluetooth communication with the DL uses the 2.4 GHz frequency band. This is the same band used
by the devices described below.
•Industrial, scientific, and medical (ISM) equipment such as microwaves and pacemakers.
• portable premises radio equipment (license required) used in factory production lines etc.
• portable specified low-power radio equipment (license-exempt)
•IEEE802.11b/IEEE802.11g standard wireless LAN devices
The above devices use the same frequency band as Bluetooth communications. As a result, using the
DL within proximity to the above devices may result in interference causing communication failure or
reduction of transmission speed.
Although a radio station license is not required for this instrument, bear in mind the following points
when using Bluetooth technology for communication.
Regarding portable premises radio equipment and portable specified low-power radio
equipment:
• Before starting transmission, check that operation will not take place within the vicinity of portable
premises radio equipment or specified low-power radio equipment.
• In the case that the instrument causes radio interference with portable premises radio equipment,
terminate the connection immediately and take measures to prevent further interference (e.g.
connect using an interface cable).
• In the case that the instrument causes radio interference with portable specified low-power radio
equipment, contact your local dealer.
When using the DL in proximity to IEEE802.11b or IEEE802.11g standard wireless LAN
devices, turn off all devices not being used.
• Interference may result, causing transmission speed to slow or even disrupting the connection
completely. Turn off all devices not being used.
Do not use the DL in proximity to microwaves.
• Microwave ovens can cause significant interference resulting in communication failure. Perform
communication at a distance of 3m or more from microwave ovens.
Refrain from using the DL in proximity to televisions and radios.
• Televisions and radios use a different frequency band to Bluetooth communications.
9
3. PRODUCT OUTLINE
However, even if the DL is used within proximity to the above equipment with no adverse effects
with regard to Bluetooth communication, moving a Bluetooth compatible device (including the DL)
closer to said equipment may result in electronic noise in sound or images, adversely affecting the
performance of televisions and radios.
Precautions regarding transmission
For best results
• The usable range becomes shorter when obstacles block the line of sight, or devices such as PDAs
or computers are used. Wood, glass and plastic will not impede
range becomes shorter. Moreover, wood, glass and plastic containing metal frames, plates, foil and
other heat shielding elements as well as coatings containing metallic powders may adversely affect
Bluetooth
• Use a vinyl or plastic cover to protect the instrument from rain and moisture. Metallic materials
should not be used.
• The direction of the Bluetooth antenna can have adverse effects upon usable range.
Reduced range due to atmospheric conditions
The radio waves used by the DL may be absorbed or scattered by rain, fog, and moisture from the
human body with the limit of usable range becoming lower as a result. Similarly, usable range may
also shorten when performing communication in wooded areas. Moreover, as wireless devices lose
signal strength when close to the ground, perform communication at as high a position as possible.

• When installing/removing the battery, make sure that moisture or dust particles do not come in
contact with the inside of the instrument.
• Remove batteries from the instrument or charger before putting into storage.
• Store the battery in a dry room where the temperature is within the following ranges
Storage period Temperature range
1 week or less -20 to 50°C
1 week to 1 month -20 to 45°C
1 month to 6 months -20 to 40°C
6 months to 1 year -20 to 35°C
For long-term storage, the battery should be charged at least once every six months.
• The BDC58/70 generates power using a chemical reaction and as a result has 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.

• Mount the battery in the instrument before performing this operation because the instrument will tilt
slightly if the battery is mounted after leveling.
6.1 Setting Up
PROCEDURE
1. Make sure the legs are spaced at equal
intervals and the head is approximately level.
Set the tripod so that the head is positioned over
the survey point.
Make sure the tripod shoes are firmly fixed in the
ground.
2. Place the instrument on the tripod head.
Supporting with one hand, tighten the centering
screw on the bottom of the unit to make sure it is
secured to the tripod.
6.2 Leveling

4. Level the DL using the leveling foot screws.
PROCEDURE Leveling with the Flat head tripod
1. Center the bubble in the circular level by either
shortening the tripod leg closest to the offcenter
direction of the bubble or by lengthening the
tripod leg farthest from the offcenter direction of
the bubble.
2. Adjust one more tripod leg until the bubble is
roughly centered.
3. Turn the leveling foot screws while checking the
circular level until the bubble is exactly centered
in the center circle. When you turn a screw
clockwise, raising the instrument, the bubble will
move towards the position of that screw.
