WARNING!
Remove the pyro unit before removing the lever unit to
avoid unintentional detonation.
2.4.1 Effective range
The effective range of the Hand Grenade Simulator is similar to that of
a real grenade. This is achieved through short range radio
transmissions from the simulator to target systems. As an option it is
possible to send laser code messages as a complement to radio.
2.4.2 Ammunition code
At detonation, the Hand grenade simulator sends an ammunition
code. Any target system that receives the message will evaluate and
calculate the effect:
• Targets close to the detonation will evaluate the hit effect according
to a hit probability (high radio signal strength).
• Targets further from the detonation will only get a sound effect
(medium radio signal strength).
• Targets far away from the detonation will not be affected (low radio
signal strength).
2.4.3 PDD status Check
When the safety lever is released, the Hand grenade simulator checks
the status of the paired PDD (i.e. the one throwing the simulator). The
function (PDD status check) is configurable (Enable/Disable). If the
PDD is not OK or killed, the ammunition code transmission is inhibited.
The detonation of the pyro is still performed.
2.5 Retrieval
A location indication on the simulator (LEDS flash white each 5 sec.)
enables retrieval of the simulator. The location indication starts 30 sec.
(configurable) after detonation and stops after a configurable duration
of time (Time location indication).
