2. Generate 1khz monophasic square wave with small positive offset of 0.25V
3. build in Battery monitor LED
4. closed circuit check, either constantly or upon starting the frequency generation
5. maximum of 2 switches (for example : Select/Start)
6. can be either analog or digital, whichever way is cheaper.
7. LED for when generating a frequency.
