Strategies for Saving Energy
The standard recording time with a fully charged battery is 120 minutes at 20 kHz and 0 dB
output power in a range of up to 5 m between headstage and receiver. Please read chapter
"Power Consumption" in the Appendix.
To prolong the recording time until the battery has to be recharged on the one hand you can
decrease the sampling frequency, on the other hand you can decrease the RF output power.
For example, when recording with 500 Hz sampling frequency you save 100 mA per hour and
the energy of the storage battery lasts for a recording time of eight hours. This may be useful
for experiments in epilepsy research.
For example, when recording with –18 dB at 20 kHz sampling frequency you save approximately
50 mA per hour, that means the recording time is 30 minutes longer compared to the time when
recording with 0 dB. However, the transmission power will decrease respectively.
Starting the W8-System again after switching off via software
To switch the headstage back on after pressing the button "Switch Off", the user has two
possibilities: Use the infrared flasher and illuminate the receiver LEDs next to the battery
connector. Then press the button "Scan" in "Wireless Window" to reconnect to the headstage.
The second possibility is to unplug the battery from the headstage manually and to reconnect
headstage and battery again.
Add a display to your rack.
The number of displayed channels depends on the number of selected channels in “Wireless”
of “Hardware” tab.
