SAFETY EARTH GROUND
A uninterruptible safety earth ground must be provided from the main power
source to the product input wiring terminals, power cord, or supplied power cord
set.
CHASSIS GROUND TERMINAL
To prevent a potential shock hazard, always connect the rear-panel chassis ground
terminal to earth ground when operating this instrument from a dc power source.
SAFETY SYMBOLS
Indicates instrument damage can occur if indicated operating limits are exceeded.
Indicates hazardous voltages.
Indicates earth (ground) terminal
WARNING A WARNING note denotes a hazard. It calls attention to a procedure,
practice, or the like, which, if not correctly performed or adhered to, could
result in personal injury. Do not proceed beyond a WARNING sign until the
indicated conditions are fully understood and met.

Safety Considerations for this Instrument
WARNING This product is a Safety Class I instrument (provided with a protective
earthing ground incorporated in the power cord). The mains plug shall only
be inserted in a socket outlet provided with a protective earth contact. Any
interruption of the protective conductor inside or outside of the product is
likely to make the product dangerous. Intentional interruption is
prohibited..
Whenever it is likely that the protection has been impaired, the instrument
must be made inoperative and be secured against any unintended operation.
If this instrument is to be energized via an autotransformer (for voltage
reduction), make sure the common terminal is connected to the earth
terminal of the power source.
If this product is not used as specified, the protection provided by the
equipment could be impaired. This product must be used in a normal
condition (in which all means for protection are intact) only.
No operator serviceable parts in this product. Refer servicing to qualified
personnel. To prevent electrical shock, do not remove covers.
Servicing instructions are for use by qualified personnel only. To avoid
electrical shock, do not perform any servicing unless you are qualified to do
so.
The opening of covers or removal of parts is likely to expose dangerous
voltages. Disconnect the product from all voltage sources while it is being
opened.
Adjustments described in the manual are performed with power supplied to
the instrument while protective covers are removed. Energy available at
many points may, if contacted, result in personal injury.
The power cord is connected to internal capacitors that my remain live for
5 seconds after disconnecting the plug from its power supply.
For Continued protection against fire hazard, replace the line fuse(s) only
with 250 V fuse(s) or the same current rating and type (for example, normal
blow or time delay). Do not use repaired fuses or short circuited fuseholders.

CAUTION: Always use the three-prong ac power cord supplied with this product. Failure to ensure
adequate earth grounding by not using this cord may cause product damage.
This product is designed for use in Installation Category II and Pollution Degree
2 per IEC 1010 and IEC 664 respectively.
This product has autoranging line voltage input, be sure the supply voltage is
within the specified range.
Ventilation Requirements: When installing the product in a cabinet, the
convection into and out of the product must not be restricted. The ambient
temperature (outside the cabinet) must be less than the maximum operating
temperature of the product by 4° C for every 100 watts dissipated in the cabinet.
If the total power dissipated in the cabinet is greater than 800 watts, then forced
convection must be used.

Calibration Procedures
Chapter 1
Calibrating The Test Set
Familiarize yourself with the CURSOR CONTROL knob.
Throughout this tutorial, the terms "position," “select,” and “set” are used to
describe the interaction of the cursor (which appears as a small, lighted
rectangular box) and the fields on the screen.
Position
To position the cursor at a field, rotate the knob to move the cursor.
Select
To select a field, position the cursor in front of a field or menu item, and then press the
cursor-control knob.
When a field is selected, a selection may be underlined, a list of choices may be dis-
played, or the field may be highlighted to indicate that it is ready for a data entry. In
some cases, a message appears at the top of the display to indicate suggested actions.
Set
To set a field, first select it, then choose a setting by either selecting from a list of
choices, underlining (such as On/Off). or making a data entry.
If you are unfamiliar with operation of the Test Set, select several fields to see the
what happens (rotate the cursor-control knob to move the cursor to any field and
press the knob), then press PRESET to reset the instrument.
1. Position
2. Select or set

Chapter 1, Calibrate the Test Set
Preset the Test Set.
Preset the Test Set.
1. If the Test Set is not powered on:
a. turn on power to the PCS Interface (if one is
connected), then...
b. turn on power to the Test Set. Wait for the Test
Set to complete its power-up routine
2. Press the PRESET key (to begin this procedure
in a known state).
Pressing the PRESET key will configure the Test Set using factory default settings, and display the CDMA
CALL CONTROL screen.
If you have the Test Set configured to operate with a PCS Interface, and you do not turn PCS Interface
power on before the Test Set, the message “PCS Interface not found. Check power, cabling or CONFIG.”
will be displayed. To correct this condition, follow the correct sequence of powering up these two units.
