• Manufacturer Part Number: xe1202
• Description: Low-power, Integrated Uhf Transceiver
• Manufacturer: ETC-unknow

The standard power up sequence from sleep to receiver mode uses a “boost” procedure; this “boost” sequence is
selected by setting the
Mode = 000
- Sleep
The typical current consumption values during the standard power-up sequence from Stand-by to Receiver Mode is
the following
The standard power up sequence from sleep to transmit mode is described in
