\begin{abstract}
This Howto outlines how to operate the HKS-TOF counters (HTOF) and 
Enge hodoscopes (Ehodo).

\end{abstract}
 
\section {Counters}

Specifications of HTOF and Ehodo are listed in Table~\ref{equip}.

\section {Operation}

You have to turn High voltage ON, and check the voltage and the current 
are normal. When the alarm of HV rings, check the HV monitor and turn 
ON the channel which is Off. You have to monitor the hit pattern and 
check if there is a counter with low statistics.  
You have to monitor gains of ADC by the histograms and call expert if 
you find a low gain.  
You have to monitor the peak position of on-time events of TDC by the 
histograms and call expert if you find an non-negligible shift.
