SIGNAL STRENGTH
The signal strength between the transmitter and receiver can be checked by using button 4. Press and
hold button 4 of the transmitter. A countdown will start from 3 to 1 then START. When it says “START”
release button 4. A row of dots will show up on the screen and they will disappear one by one as the
signal strength is being checked. Once all of the dots disappear the receiver will calculate the signal
strength and it will be transmitted back to the transmitter and displayed on the screen.
The signal strength is shown in dBm. The strongest value is -40dBm and the weakest is around -112
dBm.
If the transmitter doesn’t get an acknowledgement from the receiver it will show “Out of Range”. This
would happen if the receiver were completely out of the signal area or on another channel or not even
powered on.
If the receiver misses too many of the transmissions,
then it won’t be able to do a proper calculation of
signal strength and will send “Error”. If this is the case, then it is likely that either there is some strong
interference in the band, or the receiver is on the fringe of being completely out of range. Try changing
the frequency of the transmitter and receiver or move to a closer or less obstructed position.
CHARGING
Use only the supplied charger or one that supplies 5V and at least 1 amp of current. When the charger is
plugged into the jack the display will show “Charging” and the current battery level in %.
When pressing the power/select button normally it shows the battery level with BAT: over top of it. While
the charger is plugged in the
“BAT” will change to “CHG” to show that it is charging.
When the charger is unplugged,
the display will show “Battery” and the current level below it to show that
the charger is now unplugged. The “CHG” will change back to “BAT” in the information display.
When the battery gets to 100% charge the display will blink
“Fully Charged” every few seconds until the
charger is unplugged.
While the beacon is being transmitted the display will show the charge state with a rotating character on
the screen.
See “TX Display” under “Controls and Indicators” above
DISPLAY
At any time while the beacon is being transmitted if buttons 1 through 4 are pressed the unit will show a
status display. If no beacon is being transmitted then buttons 1, 3 and 4 will show this display and button
2 will bring up the Menu Settings. This shows the Frequency, Unit # and Battery Level as such:
FRQ-UNIT BAT:
1-1
95%
The Unit number will show 0 if no unit number has been set up yet. BAT will change to CHG if the charger
is plugged in.
LOW BATTERY
When the battery goes below 10% charge level the unit will show
an “L” rotating on the screen when the
beacon is transmitting. It is advised to charge as soon as possible. The unit will operate normally with the
charger plugged in and the display will change to a ‘+’ character for the beacon indicator.
