Range Test Random (HR 4-6s, PPM 25-35s)
This setting transmits with a
random
delay between 4 and 6 seconds for HR coding, and 25 and
35 seconds for PPM coding.
Use this setting when performing range tests using more than one transmitter, or when using a
single transmitter in areas where tagged animals are present. The random delay setting will help
to reduce the likelihood of transmission collisions in these cases.
Range Test Fixed (HR 5-5s, PPM 30-30s)
This setting transmits with a
fixed
delay of 5 seconds for HR coding and 30 seconds for PPM
coding.
Use this setting only when performing range tests using a single transmitter, and when there are
no tagged animals known to be in the area. The fixed delay setting means that transmission
collisions are likely to occur if other transmitters are within range of your receivers at the same
time.
IMPORTANT: Range Test Random and Range Test Fixed transmit profiles should only be used
for purposes of short term testing. For long term deployment, remember to change the transmit
profile back to the default (sync tag) setting.
