Selecting and connecting your antenna
Connecting your antenna
Your antenna is connected to the 6110-MP using the Antenna port (J1) on the front of the radio.
Tunable antennas like the Tactical Whip antenna (Codan Part Number: 15-00473) and Tactical
Long Wire (Codan Part Number: 15-00476) have a quick connect/release adaptor that connects to
the antenna port (J1), the quick connect/release adaptor activates the internal tuner on the radio.
Once you have connected your antenna, it is recommended that you run a Channel Tune Test
(page 12) to ensure that standing wave ratio (SWR) values are acceptable. This test is
recommended for any antenna used, including supported broadband antennas.
Sentry-H 6110-MP Operator Guide Page 9
Note: The self test will only test the control point that it was run from. If you have a 2320
handset connected to your radio, you should run the self test on both the front panel as
well as the 2320 handset.
Note: You can press PTT at any time to abort the self-test.
Testing your radio before deployment
Testing your radio before
deployment
Once assembled, the radio should be tested to ensure that everything is working correctly. The
following tests should be run before the radio is deployed. Testing involves:
• running a diagnostic self-test; and
• measuring the standing wave ratio (SWR) of your channels; and
• carrying out station-to-station on-air testing.
Running a Self Test
The Self Test allows the radio to run through a series of checks to ensure that the radio is
operating. The CP LCD and CP Keys tests require your input in order to complete.
1. Switch on the Radio (page 15).
2. Press the key.
3. Select Self Test Screen from the Function Select screen.
4. Press (Start).

5. The CP LCD test checks for any screen errors by displaying the colour and tone
states of the screen, the screen displays White, Black, Red, Green and Blue in order.
Press any key on the keypad to progress through this test.
6. The CP Keys test checks that key presses are being registered and that keys pressed
to match the correct input received by the radio. Test each key on the keypad and
confirm that the corresponding key displays on the screen. Leave the key
last as it will end the test.
7. Once the tests have completed, a summary report will display the results. Review any
failed test results and address them before deployment.
Sentry-H 6110-MP Operator Guide Page 11
Testing your radio before deployment
Measuring the Standing Wave Ratio (SWR) of your channels
The 6110-MP radio measures the forward and reflected power between the radio and the
antenna. The measured power ratio is called the Standing Wave Ratio or SWR. To ensure correct
installation, the power and SWR assessment should be performed with the radio with any antenna
you intend on using when deployed.
SWR Results can vary based on several circumstances, including the characteristics of the
antenna, the quality of the connection to ground, the frequency used, and the proximity of the
antenna to other objects. The table below shows the communication quality you are likely to
achieve with a given SWR value.
SWR Measurement Icon Description
Less than 3.0 Good
Between 3.0 and 5.0 Poor
Greater than 5.0 Unlikely to be able to communicate on this channel
Tuning Scanned Channels
To tune your currently scanned channels:
1. Hold the key for 2 seconds.
2. Press the key to start tuning.
As each channel is tested, it will display an SWR value for each channel. An icon will
appear that indicates if SWR value is at an acceptable level for transmission on the
channel.
3. Review each channel for a good SWR reading, address any poor SWR readings
before deployment.
Page 12 Sentry-H 6110-MP Operator Guide
Testing your radio before deployment
Tuning a channel or frequency
Individual channels and frequencies can also be tested for their SWR value.
To tune a single channel or frequency:
1. Select the channel or frequency you want to test from the Channel or Scratch Mode
on the Operational screen (page 19).
2. Press the key.
3. Press the Push-To-Talk (PTT) button on the H-250 or 2320 handset (page 23).
4. Check the SWR value and address any problems before deployment.
Sentry-H 6110-MP Operator Guide Page 13
Testing your radio before deployment
On-air testing
On-air testing gives a better indication of antenna operation, particularly if the operator is familiar
with the signal strengths usually received within a network. The Channel Test call (page 39) can be
used to identify the best channel between two stations. A test call between two closely positioned
stations should return call quality results close to 100%. The Channel Test call type can be made
as a 2G or 3G ALE Point-to-Point Call (page 43) or as a Selcall call (page 49)
As well as testing signal quality, making a Selective call (page 39) to other stations in your network
will allow you to test other features of your radio like Digital Voice, Encryption and Frequency
Hopping. All of which should be tested before deploying your radio into the field. Speak to your
HF Network Administrator to resolve any critical issues you are experiencing before deploying
your radio into the field.

Secure communications
Secure communications
Secure mode is a macro that toggles two optional features of the 6110-MP radio, digital voice and
voice/data encryption. By default, the secure macro will:
• activate and deactivate AES-256 encrypted digital voice and data; or
• if encryption is not available, activate and deactivate digital voice if available; or
• activate CES-128 encryption if available.
Digital Voice
When enabled on your radio, the Standard Digital Bundle (Codan Part Number: 15-10624) enables
Digital Voice. Digital Voice overcomes the potential poor voice quality that comes as a result of
atmospheric effects and interference from other equipment and transmissions. Digital Voice
brings clarity to voice communications over HF by removing the background noise that is typical
with an analogue signal. Check with your HF Network Administrator to find out if Digital Voice is
enabled on your radio.
Encryption
When enabled on your radio, encryption allows you to send secure digital voice and data over HF
using a shared key. Two types of encryption are available, AES-256, which comes with the
Advanced Digital Bundle (Codan Part Number: 15-10625) and CES-128 (Codan Part Number:
15-10642-000). Check with your HF Network Administrator to find out if encryption is enabled on
your radio.
Switching Secure on and off
DV and encryption are toggled on and off using the same key. To toggle Secure on and off:
• From the operational screen, press to toggle digital voice/encryption
Selecting a secure key
The selection of a secure key is only available when the AES-256 or CES-128 Sales Option has
been enabled.

To select a secure key, from the channel screen:
• Hold the key to navigate to the secure info screen.
• Navigate to the Select Key Index option and press or to select the
key you want to activate.
• Press to Activate the key change.
Selecting the Digital Voice rate
The Digital Voice rate or DV rate is the bitrate of vocoder used for the digital voice transmission.
Higher vocoder rates will result in a more natural-sounding voice signal at the receiving station,
but it requires better channel conditions than the lower rates. A lower vocoder rate will result in
greater processing artefacts at the receiving station but can operate in very poor channel
conditions. The range of vocoder rates are available to enable the operator to choose the best
rate for best voice quality versus channel condition
The digital voice rate is shown in status area 1 of the channel screen. The Digital Voice Rate can
be changed during voice calls.
To change the DV Rate, from the channel screen:
• Press the key. The DV current rate will display in status area 1. Repeat this
process until you have cycled through to the bitrate you desire.

Request call can be made to the TOD master station to syncronise your radio clock.
Making a 2G or 3G ALE call
Asynchronous calling
3G ALE HF networks rely on each station on the network having syncronised clocks. Time
synchronisation is achieved by using the signals from GPS satellites. If a radio is unable to receive
GPS signals, their clock will over time lose sync with the rest of the 3G ALE HF network and will
not be able to receive 3G ALE calls. If the station you are calling is not answering your call, it may
be that their radios clock is out of sync. An asynchronous call may allow you to make calls to a
station that is in this operational state.
To make an asynchronous call:
1. Press the key.
2. Press , then select Async.
3. Select a call type using the and keys.
4. Enter the address of the station you are calling.

Troubleshooting
Troubleshooting
General Troubleshooting
Below is a checklist for basic troubleshooting.
In the unlikely event you have any problems with your 6110-MP radio, check that:
• all connectors are dry and free from dirt
• all connections are sound
• the battery pack is connected to the radio and has some charge
• the selected antenna is appropriate for the distance over which you want to
communicate
• the antenna is deployed correctly, oriented in a suitable direction, and connected to
the radio
• the grounding system is adequate as per instructions provided with the antenna
• the antenna type on the channel screen matches the type of antenna you are using
If required, restart your radio to invoke self-testing. The self-test checks the memory, hardware,
LCD and keys. If a serious fault is reported, contact your HF Network Administrator. Below is a
table with some general tips on troubleshooting your radio.

Press PTT.
If you are using a whip or long wire antenna, go to the menu screen,
then select User Data > Peripherals > Antenna Type, check that the
antenna selection icon is set to Auto Detect or Always Tune.
If you are communicating over a short distance, try laying the whip
horizontally for near vertical incident skywave operation.
If you are communicating over a long distance, try selecting an antenna
(page 8) with better performance for the distance you are trying to
transmit.
The radio is not adequately earthed. Attach an earth lead or
counterpoise as per the instructions provided with the antenna.
Troubleshooting
Problem Solution
GPS is not working Ensure that the front panel of the radio, and hence the GPS antenna, is
facing the sky so that it can receive signals from satellites. Alternatively,
connect a GPS antenna to the GPS port (J4) and place the antenna so
that it is facing the sky.
