1.SAFETY PRECAUTIONS AND GENERAL WARNINGS
MARK
This instrument is in conformity with the following standards and regulations:
•ELECTROMAGNETIC COMPATIBILITY (EMC):
EN55011 EN61000-3-2 EN61000-3-3 EN61000-4-2 EN61000-4-3
EN61000-4-4 EN61000-4-5 EN61000-4-8 EN61000-4-11 ENV50204
•SAFETY:
EN61010-1
The below-indicated safety precautions and general warnings must be carefully observed during
all phases of use and maintenance of the instrument in order to prevent from damaging people,
animals and property.
UNAOHM S.r.l. assumes no responsibility for incorrect use of the instrument or
in case the specified rules are not complied with.
1.1. SAFETY PRECAUTIONS
•Supply the instrument with a voltage which complies with the limits set out in the Specifications.
•Insert into a standard socket the three-pole power cable, provided as standard and equipped
with valid electric protection ground (the instrument belongs to Class 1).
•Do not use the instrument unless completely housed with all covers.
•The instrument has been designed to be used in covered environments. Do not expose it to rain
or dripping.
•Do not use the instrument in explosive atmosphere made up of gas, vapours, fumes and
flammable dusts.
•The instrument may be used in over-voltage Category II and Pollution Degree 2.
•Do not switch on the instrument immediately after taking it from a hot to a cold environment, in
order to avoid condensation.
•Do not either obstruct possible cooling slits or place the instrument next to heat sources.
•For prolonged use in labs or fixed positions, the instrument may be removed from its carrying
case to enable a better heat dissipation.
•Do not apply to the input connectors a DC or RF voltage higher than indicated.
•It is recommended to periodically check the carrying strap, the related fasteners and spring hooks
which may be damaged by use. As soon as signs of wear appear, replace these parts.
•For instruments with battery installed on them:
1° ) Do not short-circuit the battery, since it may explode.
2° ) Do not dip the battery into water or throw it into the fire.
3° ) Do not perforate or try to open the battery.
4° ) If replacing is necessary, use an original spare and throw the old battery away into the
dedicated containers.
5° ) Do not connect the battery with reversed polarity.

AP301-FULL-HD_rev.09_UK 5
1.2. GENERAL WARNINGS
•The liquid of the monitor is harmful. If the module breaks and the liquid eventually
comes out, do not touch with your hands or any part of your body, especially eyes and
mouth. In any case, wash immediately with water and soap.
•Do not expose the LCD to direct sunlight or to intense ultraviolet rays for a long time. It
might deteriorate.
•Keep the instrument in a place where the temperature is higher than the minimum
storage temperature, otherwise the liquid inside the crystal solidifies and causes damage
to the monitor. Where temperatures are higher than the maximum storage temperature,
as well, the liquid inside the crystal returns to the isotropic state and the process could
be non-reversible.
•One of the most common causes of demand for technical support are internal short-
circuits, due to even tiny outer bodies which may enter the instrument, despite all
precautions to avoid it. Therefore it is strongly recommended not to cut coaxial cables
near the instrument, since even very small pieces of wire from the shielding braid could
fall into the instrument and thus provoke occasional short-circuits, not easily-detectable
by technicians.
1.3. MAINTENANCE
Permitted interventions are only: connection or replacement of the battery and/or fuses,
and insertion of internal accessories as specified in the manual.
The opening of the instrument and possible servicing must be carried out only by qualified
personnel or by operators with basic electrotechnical and electrical safety knowledge.
•Disconnect the power-supply cable before servicing.
•For instruments with battery, please refer to paragraph 1.1.
•Replace fuses with specified value and type.
•Do not come into contact with circuits keeping electric charge, although not power-
supplied (capacitors).
•Take appropriate measures against the accumulation of electrostatic charges. Do not
touch internal circuits unless wearing the special antistatic strap.
•To clean external surfaces:
1° Remove the power-supply cable.
2° Use a soft cloth. Use non-aggressive liquid detergents and avoid hydrocarbon-based
products.
3° Make sure liquids or other substances do not penetrate into the instrument.

1.4. NOTES
•Some bright dots (pixels) may remain fixed on the LCD screen. These shall be considered
as normal and they are within the manufacturing tolerances.
•The specified tolerances refer to an instrument at normal usage temperature
(approximately 10 minutes after switching on).
•Prevent the instrument from falling and from suffering strong shocks; when the
instrument is carried on vehicles, place it onto a non-rigid support in order to avoid
strong vibrations.
•It is recommended to carefully read the instructions of this user manual before using the
instrument.
•This instrument may be used either on horizontal or on vertical position, seated on the
bottom.
•It is strongly recommended to regularly check the instrument (at least once a year) and
make it be calibrated.
Furthermore, the replacement of worn-out bags and straps is highly suggested in order
to avoid mishaps, as per paragraph 1.1.

4.INSTRUCTIONS FOR USE
The field strength meter may be powered in three modes:
1) From the AC mains network by means of an external power supply. The power supply
accepts mains voltage ratings of 90V to 260 V. The protection fuses are internal and are
not accessible.
⇒NOTE: In the event that any of these fuses should burn out, do not attempt to replace
them: send the power supply to the manufacturer's assistance centre for testing.
Insert the power cable into the DC power supply’s input connector. The Ch indicator on
the front panel will light up, indicating that the device is receiving power and the battery
is charging. The indicator light will be either green or red, indicating one of the following
conditions:
Green = battery charge complete
Red = battery charging
Flashing Red = battery charging procedure reduced or suspended due to an extremely
low battery charge or temperature.
In this situation, the device is receiving electrical power and is waiting to be turned on
(Stand-By).
2) From the battery.
3) By means of an external Vdc power source, between 11.5V and 15V, capable of
providing at least 3 A (using the same input as that which is used for the external power
supply).
4.1. TURNING THE DEVICE ON/OFF
Press the button to turn the instrument on. In order to shut the device off, hold the
same button down for a few seconds.
This procedure ensures that the data saved during the work session will remain in the unit’s
non-volatile memory and that the device will return to the same operating mode when
turned back on.
4.2. USE OF BATTERY
If the supplied external DC is enough, the instrument automatically recharges its internal
battery, when it is on stand-by mode.
Some important notes about the use of batteries:
•It is recommended to recharge the battery when the instrument is new
•When the battery is almost totally flat, before the instrument is unserviceable the battery
icon on the upper left side of the screen becomes red. In this case it is recommended to
stop using the instrument as soon as possible and recharge its battery. If you persist in
using it (5 ÷10 minutes max), the instrument switches off.
•When the instrument remains unoperational for long, it is suggested to recharge the
battery at least once a month, in order to offset the auto-discharge.
•It is recommended to switch on the instrument at least once a month, and keep it
switched on a few hours to recharge the battery of its internal clock.

AP301-FULL-HD_rev.09_UK

4.2.1.BATTERY STATUS
In order to know the charge level of the battery and thus the remaining autonomy, look at
the battery icon on the screen, in the upper part on the left.
4.2.1.1. PREPARING THE INSTRUMENT FOR USE
The instrument switches on in the same mode in use when it was switched off, the only
exceptions being:
•For safety reasons, output voltage from the input connector RF IN (5) is always
excluded.
•The status of digital boards QPSK , OFDM and QAM is not re-established.
Every time a key is pressed, a short acoustic note confirms this operation.
This acoustic note can be deactivated from the main menu, selecting the item “BUZZER”.
4.3. AUDIO/VIDEO SETTINGS
In order to adjust volume, brightness, contrast, colour, buzzer volume and tone, press
several times the key until the desired adjustment appears. Modify its value turning
the shaft encoder. Press ENTER to confirm it or just wait for time out.
4.4. TUNING
Tuning can be carried out by frequency, by channel or by program. To select one of these
modes, press the corresponding key: PR for program, CH for channel, FR for frequency to
alternate between channel mode and frequency mode. The indicator corresponding to the
selection flashes on the status bar. Whichever mode is selected, tuning is carried out
turning the shaft encoder or inserting values through the alphanumeric keypad. Press
ENTER to confirm setting.
In satellite band, the frequency display, from 1st IF to transponder frequency, can be
alternated pressing the LO key.
Moreover, using the TP SAT function in the side menu (which is activated pressing ENTER
when the instrument is in satellite band), satellite transponders’ tuning is carried out
selecting the transponder number.
To select the desired satellite, press keys 2nd and TP SAT and select the item SATELLITE
in the menu shown on the screen. Then press ENTER.
Turn the shaft-encoder to highlight the desired satellite, then press ENTER again to confirm
it.

4.4.2.USE OF LOCAL OSCILLATORS (LO)
Pressing more times the LO key, the satellite frequency will be displayed as follows
(depending on the selection):
FOR “LO DEFAULT”:
•1st IF: 1st IF frequency is displayed
•LO 1: the tuned frequency related to the 9750 MHz local oscillator is displayed
•LO 2: the tuned frequency related to the 10600 MHz local oscillator is displayed
FOR “LO USER":
•1st IF: 1st IF frequency is displayed
•LO 1: the tuned frequency related to the set local oscillator is displayed
•LO 2: the tuned frequency related to the set local oscillator is displayed
•LO 3: the tuned frequency related to the set local oscillator is displayed
•LO 4: the tuned frequency related to the set local oscillator is displayed
4.4.2.1. CHECK THE CHANNELIZATION IN USE
Keeping the CH key pressed, the menu appears on the screen. Select CHANNEL TABLE to
check the channelization in use.
4.5. PROGRAM STORAGE
Remember that stored programs are used also by the Data Logger.
In order to store a frequency or channel in one of the 100 available storage locations,
proceed as follows:
I. Set the program number where the frequency (or channel) must be stored
II. Set the frequency (or channel)
III. Press the “2nd” key and then the STORE key
IV. Make the same to store further programs.
PLEASE NOTE: if the LNB power-supply voltage is inserted when storing, this will
be applied by the Data Logger, and not by the direct recall of a program.
⇒The channel storage requires, besides the acquisition of video/audio carriers, also the
acquisition of other parameters such as "BW" (bandwidth), "STD" (TV standard).
Therefore, when you recall a program with SAT frequency from the memory, also video
and audio are displayed; it is recommended to first tune the desired audio subcarrier,
before storing a SAT channel.
4.5.1. PR ENGAGED MENU
Keeping the PR STORE key pressed, you enter the menu for inspection/modification of
stored channels. Once you have carried out the desired operations, press PR STORE again
to exit menu.
