performance.
Charging Battery
• Be sure to charge the battery within the charging temperature range.
Charging temperature range: 0 to 40°C
• Use only the specified battery or the battery charger. Failures caused by using other batteries or battery
chargers are out of warranty including the main unit.
Warranty policy for Battery
• Battery is an expendable item. The decline in retained capacity depending on the repeated charging/
discharging cycle is out of warranty.
Telescope
• Aiming the telescope at the sun will cause internal damage to the instrument. Use the solar filter when
observing the sun.
“20. SPECIAL ACCESSORIES”
Tribrach Clamp and Handle
• When the instrument is shipped, the tribrach clamp is held firmly in place
with a locking screw to prevent the instrument from shifting on the tribrachs.
Before using the instrument the first time, loosen this screw with a precision
screwdriver. And before transporting it, tighten the locking screw to fasten
the tribrach clamp in place so that it will not shift on the tribrachs.
• The handle of the instrument can be removed. When operating the
instrument with the handle attached, always make sure that the handle
is securely fixed to the instrument body with the handle locks.
Precautions concerning water and dust resistance
GM conforms to IP66 specifications for waterproofing and dust resistance when the battery cover and external interface
hatch are closed and connector caps are attached correctly.
• Be sure to close the battery cover and external interface hatch, and correctly attach the connector caps to
protect the GM from moisture and dust particles.
The specification grade for water proofing and dust resistance is not guaranteed when using USB connector.
• Make sure that moisture or dust particles do not come in contact with the inside of the battery cover, terminal
or connectors. Contact with these parts may cause damage to the instrument.
• 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.
• If there is a crack or deformation in the rubber packing for the battery cover or external interface hatch, stop
using and replace the packing.
• To retain the waterproof property, it is recommended that you replace the rubber packing once every two
years. To replace the packing, contact your local dealer.
The Lithium Battery
• This instrument contains lithium battery. It lasts for approximately 5 years of normal use and storage
(Temperature = 20°C, humidity = about 50%), but its lifetime may be shorter depending on circumstances. To
replace the lithium battery, contact your local dealer.
Vertical and horizontal clamps
• Always fully release the vertical/horizontal clamps when rotating the instrument or telescope. Rotating with
clamp(s) partially applied may adversely affect accuracy.
v
Tribrach
• Always use the tribrach provided. During a traverse observation, it is recommended to use the same type of
tribrach for the target as well for accurate observations.
Backing up data
• Data should be backed up (transfered to an external device etc.) on a regular basis to prevent data loss.
Other precautions
• Close the external interface hatch and battery cover before starting measurement. Otherwise, ambient light
entering the USB port may adversely affect measurement results.
• If the GM is moved from a warm place to an extremely cold place, internal parts may contract and make the
keys difficult to operate. This is caused by cold air trapped inside the hermetically sealed casing. If the keys
do not depress, open the battery cover to resume normal functionality. To prevent the keys from becoming
stiff, remove the connector caps before moving the GM to a cold place.
• Never place the GM directly on the ground. Sand or dust may cause damage to the screw holes or the
centering screw on the base plate.
• Do not aim the telescope directly at the sun. Also, attach the lens cap to the telescope when not in use. Use
the Solar filter to avoid causing internal damage to the instrument when observing the sun.
“20. SPECIAL ACCESSORIES”
• Do not perform vertical rotation of the telescope when using the lens hood, diagonal eyepiece, or solar filter.
Such accessories may strike the instrument causing damage.
• Protect the GM from heavy shocks or vibration.
• Never carry the GM on the tripod to another site.
• Turn the power off before removing the battery.
• When placing the GM in its case, first remove its battery and place it in the case in accordance with the
layout plan.
• 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.
vi
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 silicon cloth.
• If the display unit is dirty, carefully wipe it with a soft, dry cloth. To clean other parts of the instrument or the
carrying case, lightly moisten a soft cloth in a mild detergent solution. Wring out excess water until the cloth
is slightly damp, then carefully wipe the surface of the unit. Do not use any alkaline cleaning solutions,
alcohol, or any other organic solvents, on the instrument or display unit.
• Store the GM in a dry room where the temperature remains fairly constant.
• Check the tripod for loose fit and loose screws.
• If any trouble is found on the rotatable portion, screws or optical parts (e.g. lens), contact your local dealer.
• When the instrument is not used for a long time, check it at least once every 3 months.
“18. CHECKS AND ADJUSTMENTS”
• When removing the GM from the carrying case, never pull it out by force. The empty carrying case should be
closed to protect it from moisture.
• Check the GM for proper adjustment periodically to maintain the instrument accuracy.
Bluetooth Wireless Technology
• Bluetooth function may not be built in depending on telecommunications regulations of the country or the
area where the instrument is purchased. Contact your local dealer for the details.
• Use of this technology must be authorized according to telecommunications regulations of the country where
the instrument is being used. Contact your local dealer in advance.
• 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.
“25. REGULATIONS”
Radio interference when using Bluetooth technology
Bluetooth communication with the GM 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/IEEE802.11n standard wireless LAN devices
• The above devices use the same frequency band as Bluetooth communications. As a result, using the
GM 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 Bluetooth function in proximity to IEEE802.11b/IEEE802.11g/IEEE802.11n standard wireless
LAN devices, turn off all wireless LAN devices not being used.
• Interference may result, causing transmission speed to slow or even disrupting the connection
completely.
vii
Do not use the GM in proximity to microwaves.
• Microwave ovens can cause significant interference resulting in communication failure. Perform
communication at a distance of 3 m or more from microwave ovens.
Refrain from using the GM in proximity to televisions and radios.
• Televisions and radios use a different frequency band to Bluetooth communications. However, even if the
GM is used within proximity to the above equipment with no adverse effects with regard to Bluetooth
communication, moving a Bluetooth compatible device (including the GM) 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 communication but the usable 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
communication and concrete, reinforced concrete, and metal will render it impossible.
• Use a vinyl or plastic cover to protect the instrument from rain and moisture. Metallic materials should not
be used.
Reduced range due to atmospheric conditions
• The radio waves used by the GM 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.
• TOPCON CORPORATION cannot guarantee full compatibility with all Bluetooth products on the market.

Sighting collimator
Use sighting collimator to aim the GM in the direction of the measurement point. Turn the
instrument until the triangle in the sighting collimator is aligned with the target.
A gun sight is mounted on Face 2 position of the iM-55. Align the telescope to the direction of the
target in such a way that the gun sight is positioned with the target as shown below. Note that you
see the target at a distance from the gun sight.
Horizontal direction: a position where you can see both the target and back sight at the center of
the front sight's slit.
Vertical direction: a position where you can see the tops of the front sight and back sight at the
same height of the target's center.
Instrument height mark
The height of the GM is as follows:
• 192.5 mm (from tribrach mounting surface to this mark)
• 236 mm (from tribrach dish (TR-103R) to this mark)
"Instrument height" is input when setting instrument station data and is the height from the
measuring point (where GM is mounted) to this mark.
Laser-pointer Function
A target can be sighted with a red laser beam in dark locations without the use of the telescope.

Lighting and Extinguishing of Laser Pointer
Whenever the {F3} key is pressed, the laser pointer will light up or be extinguished, in that order.
The laser pointer assists with collimation by radiating visible laser light from the objective lens to the
target.
• The laser pointer indicates the approximate collimation position of the telescope. It does not
indicate the exact collimation position.
• You cannot see the laser pointer when looking through the telescope. Therefore, please look
directly, with the naked eye, at the point indicated by the laser pointer.
• The distance to which the laser pointer can be used will vary with climatic conditions and with
the eyesight of the user.
• When the laser pointer is used, the operating time of internal power source will become short.
Tilt correction
The tilt setting mode performed here will not be memorized after powering OFF. To set TILT
correction in the initialized setting (it is memorized after powering OFF), see Section 6.4.3 “Vertical
and Horizontal Angle Tilt correction (Tilt ON/OFF)”.
Set audio mode
The light acceptance quantity level (Signal level) is displayed in this mode.
When reflected light from the prism is received, a buzzer sounds. This function is good for easy
collimation when the target is difficult to find.
Press the {F4} key to view the set audio screen.
To stop the buzzer, refer to Chapter 17 “SELECTING MODE”.
Also, it is possible to display the signal level in Distance Measuring Mode.
The temperature, pressure, PPM, PSM,NPM and SHT can be viewed in set audio mode.
Refer to Chapter 10 “SET AUDIO MODE”, Chapter 11 “SETTING THE PRISM CONSTANT
VALUE” and Chapter 12 “SETTING ATMOSPHERIC CORRECTION”, for further instructions.

2.2 Battery Power Remaining Display
Battery power remaining display indicates the power condition.
• The battery operating time will vary depending on the environmental conditions such as ambient
temperature, charging time, the number of times of charging and discharging etc. It is
recommended for safety to charge the battery beforehand or to prepare spare full charged
batteries.
• For general usage of the battery, see Chapter 14 “POWER SOURCE AND CHARGING”.
• The battery power remaining display shows the power level regarding to the measurement mode
now operating.
The safety condition indicated by the battery power remaining display in the angle measurement
mode does not necessarily assure the battery's ability to be used in the distance measurement
mode.
It may happen that the mode change from the angle mode to the distance mode will stop the
operation because of insufficient battery power for the distance mode which consumes more power
than angle mode.

2.3 Vertical and Horizontal Angle Tilt Correction
When the tilt sensors are activated, automatic correction of vertical and horizontal angle for
mislevelment is displayed.
To ensure a precise angle measurement, tilt sensors must be turned on. The display can also be used
to fine level the instrument. If the (TILT OVER) display appears the instrument is out of automatic
compensation range and must be leveled manually.
• GM compensates both the vertical angle and the horizontal angle readings due to inclination of the
standing axis in the X and Y directions.
• The display of Vertical or Horizontal angle is unstable when instrument is on an unstable stage or a
windy day. You can turn OFF the auto tilt correction function of V/H angle in this case.
• To set auto tilt correction from the moment that power is on, See Section 6.4.3 “Vertical and
Horizontal Angle Tilt correction (Tilt ON/OFF)”.
