Cleaning
Wipe the headstage connector with a damp cloth to clean salt spills. Avoid spilling
liquids on the headstage. The Teflon input connector should be kept very clean.
Effective cleaning can be done by spraying with alcohol or swabbing carefully with
deionized water.
Static Precautions
The headstage can normally be safely handled. However, if you are in a laboratory
where static is high (i.e. you hear and feel crackles when you touch things) you should
touch a grounded metal object immediately before touching the headstage.
Acoustic Pick-up
Rare cases have been reported in which the headstage was susceptible to low amplitude
acoustic pick-up. For example, the audible hum of a nearby isolation transformer can
acoustically couple to the input of the headstage. This was traced to the silver wire of
the electrode and was solved by trimming off a fraction of the wire, thus changing its
resonant frequency.
