neutral connection may result in a serious electrical shock to the user 
which can cause serious bodily injury or death. 
 

Reset Push-button: 

1.

 

At any time, the circuit can be reset by pressing the push-button located at the 
top right-hand corner of the main PCB. 

2.

 

Pressing the reset push-button will result in the title screen being immediately 
displayed on the LCD screen.  The band mode will then need to be re-chosen 
before the frequency can be entered.

 

Warranty Information: 

 

It is difficult to extend warranties on a kit that is designed to be assembled by the user. 
Therefore, neither Tablerock Instruments, nor any principal or agent of that company 
has elected to provide any written or implied warranty, either "limited" or "full", rather 
than to attempt to comply with the provisions of various state and federal laws and 
regulations.  To the fullest extent allowed by law, all implied and express warranties of 
merchantability, fitness for a particular purpose and any other type of warranty are 
disclaimed.  Instead, we would invite customers to contact us and describe the nature 
and extent of any problem that they may have with this product.
