6.5 Duty Cycle
Duty cycle is the percentage of transmission time in a complete transmission cycle (i.e. transmission and
non-transmission combined).
non-transmission combined).
Duty Cycle (%) = (transmission time/complete cycle time)x100
The Mini-Beacon 1000 can be configured for 10% or 17% duty cycle. Duty cycle configuration is
accomplished using switches #6, #7 on the 8 position DIP switch. Table 2: 8 Position DIP Switch,

Increasing duty cycle for a given pulse duration will decrease battery life.
