1. Know technical information about a rangeof products, testing procedures
and associated activities, equipment to be used and thereasons for the test
How to select tests andcollect relevant andsufficient informationfor the
test tobe successful
Testing radio equipment in a signalenvironment is essential to making sure
that the equipment is functioning correctly and that any problems with it are
identified and remedied to enable the user to have efficient useof the
equipment.
I have done this many times. Itcan firstbe done by checking the exterior of the
radio for any dents, cracks or interior protruding objects, checking of the
connector ports and terminals for damage. A big thing to look for is the anti-
tamper seals on the radio if these are broken or snapped it may identify that
someone has been using the radio equipment incorrectly or tampering with it.
This would have to be passed uop to the chain of command and reported. For
the radio its self-turning it on and testing it is very simple by turning it on the
radio will commence a self BIT(built in test) and will initialise and confirm that
this has happened by a beeping sound being emitted from the head set.

2. How to minimise servicedisruptionduring testing andavoid detrimental
effects of changes toperformance
To do this once I have full tested the radios I am using I have had to set up the
frequency’s for the radios in use and have them in separateareas in order to
make surethat the signals do not interfere with any broadcastand send a
message/transmission to the other radio.
To help minimize any disruption you can also
 Be in line of sightto one another
 Switch the radios to a higher power setting
 Avoid dead spots/dead ground
 Move away fromlarge objects such as buildings
 Use a different type of antenna
Ways toconfigure tests
Each test for radio equipment is differentand has differentfunctions. I have
had to configurea normal bowman radio for a patrol you would haveto carry
out the normaltests and make sureall the information imputed into the radios
is correctand recent, to configureit to another radio or to the OPS room for
example the user sends a radio check to the relevant call sign they wish to
reach and gain a reply, this will indicate that the radio is sending and receiving
correctly, this is also carried out routinely on any task the user is on.

3. How to record, maintainor restore configurations, dataand functionality
To record information about configurations say a frequency or fixed frequency
periods there are guidelines issued out to each unit using the equipment these
also include data encryptions. Theseare recoded and used for the purposes of
the users to have the information to hand. In the past I havehad to set a radio
up to two different radio networks this allowed me to listening in to two
different nets simultaneously the information is stored on the UCD once the
radio has been given the correctinformation.
Types of service level agreements
This covers a wide aspect in signals from basic user maintenance to data
encryption. The service level all depends on the type of equipment in use, for a
5.1mmastthis would haveto be routinely checked and tested for functionality
and meet with the required demands of its function.
Individual responsibility andauthority
Individualresponsibility (as mentioned above) checks and maintenance of
equipment is in the hands of the issuer, holder and of coursea user which I
have often done. If you think about it the responsibility for any said item is in
the hands of the user at the time.
Escalation procedures and risks associated with using a
testing process
During any testing process thereare risks involved, during a BIT(built in test)
on the bowman radio systemit may fail due to internal faults, or poorly
connected equipment (i.e. antenna). Many of these risks can be treated by the
user’s correctknowledgeand self-help, many others such as internal failures
with the inner working of the radio itself result in the radio having to be sent
back to the company who built it to be repaired.

4. Describe the purposes of testing
Aiding the diagnosis process
In order to help achieve a successfuldiagnosis I would haveto firstcheck all
equipment for visual signs of damage/damages and anything that could alter
or affect any test.
Aiding in this you could use two people one would set up and preparethe
radio and the other would be checking for faults, (i.e. radio checks, channel,
power setting etc.)
As seen here in this picture this radio has been set up for a vehicle fitting. Doin
this isn’tdifficult but can resultin problems if not done correctly. Its power
supply is direct fromthe vehicle which would have to be connected properly to
test this you can turn on the vehicle and switch on the power for the radio at
the baseof its station which will be indicated by the LED turning on.

Comparing actual and expected performance
I have done this before with 2 bowman radios. We checked the
range of the radio at different power settings and adjusted
them accordingly.
We had previously checked the distances and power settings
before trying this exercise and found that at each different
range depending on weather and obstacles that the radio
frequency can travel at the required distance on that power
setting. Which was just a bit further than the said distance.
