Care and maintenance
Before using the instrument, read and follow the following maintenance instructions.
The Focus 4 total station is a precision instrument that you should store, use, and
clean in an appropriate way.
CCAUTION – The battery pack contains a Lithium-ion battery. When disposing of the
battery pack, follow the laws or rules of your municipal waste system. For more
information on the safety warnings associated with the Lithium-ion battery, see
Rechargeable Lithium-ion (Li-ion) batteries, page 5.
CCAUTION – Store the battery pack with the battery pack discharged.
Environmental conditions
•Do not leave the instrument in direct sunlight or in a closed vehicle for
prolonged periods. Overheating the instrument may reduce its efficiency.
•If the total station has been used in wet conditions, immediately wipe off any
moisture and dry the instrument completely before returning it to the carry
case. The Focus 4 total station contains sensitive electronic assemblies which
have been well protected against dust and moisture. However, if dust or
moisture gets into it, severe damage could result.
•Sudden changes in temperature may cloud the lenses and drastically reduce the
measurable distance, or cause an electrical system failure. If there has been a
sudden change in temperature, leave the instrument in a closed carry case in a
warm location until the temperature of the instrument returns to room
temperature.
Storage
•Do not store the total station in hot or humid locations. In particular, you must
store the battery pack in a dry location at a temperature of less than 30 °C
(86 °F). High temperature or excessive humidity can cause mold to grow on the
lenses. It can also cause the electronic assemblies to deteriorate, and so lead to
instrument failure.
•Store the battery pack with the battery discharged.
•When storing the instrument in areas subject to extremely low temperatures,
leave the carry case open.
•If the tribrach will not be used for an extended period, lock down the tribrach
clamp knob and tighten its safety screw.
•The carry case is designed to be watertight, but you should not leave it exposed
to rain for an extended period. If exposure to rain is unavoidable, make sure that
the carry case is placed with the Spectra Precision nameplate facing upward.
1 Introduction
20 Spectra Precision Focus 4 Total Station User Guide
Cleaning
•Do not use organic solvents such as ether or print thinner to clean the
non-metallic parts of the instrument, such as the keyboard, or the painted or
printed surfaces. Doing so could result in discoloration of the surface or in
peeling of printed characters. Clean these parts only with a soft cloth or tissue
that is lightly moistened with water or a mild detergent.
•To clean the optical lenses, lightly wipe them with a soft cloth or a lens tissue
that is moistened with alcohol.
Adjusting and tightening
•When adjusting the leveling screws, stay as close as possible to the center of
each screw’s range. The center is indicated by a line on the screw.
•The reticle plate cover has been correctly mounted. Do not release it or subject
it to excessive force, for example in an attempt to make it watertight.
•Before attaching the battery pack, make sure that the contact surfaces on the
battery and Focus 4 total station are clean.
•Securely press the cap that covers the data output/external power input
connector terminal. The instrument is only watertight if the cap is attached
securely or when the data output/external power input connector is used.
•The Focus 4 total station is not watertight when the data output/external power
input connector is used.
•Static electricity from the human body, discharged through the data
output/external power input connector, can damage the instrument. Before
handling the instrument, touch any other conductive material once in order to
remove static electricity.
•Be careful not to pinch your finger between the telescope and trunnion of the
instrument.

Applying power
Plug in the charger to the supplied AC adapter to turn the unit on. The power input
must be 5 V with at least 4 A of current capability. Each battery may take up to 2 A
while charging.
Charging the battery
Slide a battery into either battery slot to begin charging. The adjacent charge indicator
will illuminate yellow when charging is in progress. The charge indicator will change to
green when charging is complete.
Take note of the following:
•Charger slots are completely independent so a battery may be inserted
regardless of what is occurring in the other battery slot.
•Charging may take 2-4 hours if the battery was normally discharged.
•Charging may take up to 5 hours with a completely drained battery which has
been stored for several months without use.
•If the charge indicator(s) are blinking, there is a problem with the battery or with
the charger.

• Lithium-ion batteries should not be charged above 40 °C to 45 °C (104 °F to
113 °F). A blinking charge light may mean that the batteries are too hot for
charging. Charging will resume after the batteries cool down.
Conditioning / calibrating a battery
You must calibrate the battery (“condition”) once every 6 months or more often if
required. Calibration ensures that the reported remaining battery charge is accurate.
To start calibrating a battery, hold down the calibration button on the unit and then
insert a battery. Only the battery that was inserted while the button is pressed begins
calibration.
During battery calibration, the battery will be charged, discharged completely, and
then recharged again. Calibration should complete in approximately 17 hours. Do not
cover the charger vents during a calibration cycle.
•The blue calibration indicator light(s) blink slowly (on 1.5 sec, off 2 sec) while
calibration is in progress. The charge light(s) may be on or off during the
calibration cycle if the case temperature does not get too high.
•When a calibration cycle is completed, the calibration light stops blinking but
remains on until the corresponding battery is removed.
•Case temperature:
–The temperature of the bottom case may continue to climb to
approximately 43 °C before temperature regulation is enabled to keep the
case from becoming warmer. As the battery voltage drops, the case cools
down and the automatic temperature limiting is no longer necessary. This
minimizes the time required to discharge a battery.
–If the case temperature continues to become too hot internally, even after
temperature regulation is enabled, there is a secondary failsafe that aborts
the calibration completely. If an abort occurs, the calibration light(s) blink
rapidly and battery charging is re-enabled.

Focusing the telescope
CWARNING – Never look at the sun through the telescope. If you do, you may damage or
lose your eyesight.
When you sight the instrument, you aim the telescope at
the target, bring the target image into focus, and align the
image with the center cross-hairs of the reticle.
To sight the instrument:
1. Adjust the diopter:
a. Aim the telescope at a blank area, such as the
sky or a piece of paper.
b. Looking through the eyepiece, rotate the
diopter ring until the reticle cross-hairs are in
sharp focus.
2. Eliminate parallax:
a. Aim the telescope at the target image.
b. Rotate the focusing ring until the target image is in sharp focus on the
reticle cross-hairs.
c. Move your eye vertically and laterally to check whether the target image
moves relative to the reticle cross-hairs.
–If the target image does not move, there is no parallax.
–If the target image does move, rotate the telescope focusing ring and repeat
Step 2c.
3. Rotate the tangent screw. The final turn of the tangent screw should be in a
clockwise direction, to align the target accurately on the center cross-hairs.

Setting the measurement mode and preparing the target
The Focus 4 total station has two measurement modes: Prism mode (Prism) and
Reflectorless mode (N-Prism). To change the mode at any time from any observation
screen, hold down [MSR1] or [MSR2].
Set the measurement mode depending on the target that you want to measure, as
shown here.
In some cases, you can measure to another target that is not appropriate to the set
measurement mode.
Note – The Focus 4 total station is Laser Class 1 in the measurement function, and Laser
Class 2 in the Laser Pointer function. Do not sight the prism when the Laser Pointer is on.
Measurement with a prism
As the Focus 4 total station is extremely sensitive, multiple reflections on the prism
surface can sometimes cause a significant loss in accuracy.
To maintain the accuracy of your measurements:
•Use a prism with thin edges.
Do not use a prism with scratches, a dirty surface, a chipped center, or thick
edges.

•When measuring a short distance, incline the prism slightly so that the EDM
can ignore unnecessary reflections on the prism surface, as shown below.
•Hold the prism securely in place and do not move while taking measurements.
In Prism mode, to avoid false measurements on objects other than the prism or
reflector-sheet, targets that are less reflective than the prism or reflector sheet are not
measured. Even if you start a measurement, measured values are not displayed. To
measure less reflective objects, use the N-Prism (Reflectorless) mode.
Measurement in reflectorless (N-Prism) mode
The Focus 4 total station enables reflectorless measurements up to 300 m (984 feet).
The intensity of the reflection from the target determines the distance the Focus 4
total station can measure in this mode. The color and condition of the target surface
also affect the measurable distance, even if the targeted objects are the same. Some
less-reflective targets may not be measured.
The following table describes some examples of targets and approximate measuring
distances:
Measurable distances may be shorter or measurement intervals may be longer if either
of the following conditions apply:
•the angle of the laser against the target is small
•the surface of the target is wet
In direct sunlight, the measurable distance may be shorter. In this case, try to throw a
shadow on the target.
Targets with completely flat surfaces, such as mirrors, cannot be measured unless the
beam and the target are perpendicular to each other.
Target You can measure approximately...
Traffic signs, reflectors 500 meters (1640 feet)
Paper (white), veneer (new) 300 meters (990 feet)
wall (brightly painted), brick 100 to 200 meters (330 to 660 feet)
