What me, read a manual?

Before you begin, please make sure you read the Safety Instructions on page 2 and 

Getting Started on page 4. 

Your new TAPCO

®

 T•231 is designed to set up quickly and operate easily. We know it’s 

often seen as a sign of weakness to read a manual, along with asking for directions when 
lost, but maybe you can read the rest when nobody is looking. 

It is important to keep your receipt in a safe place, and not a bad idea to write your 

product information here for future reference (i.e., insurance claims, tech support, return 
authorization, etc.).

  Exposure to extremely high noise levels may cause permanent 

hearing loss. Individuals vary considerably in susceptibility to 

noise-induced hearing loss, but nearly everyone will lose some 

hearing if exposed to suffi ciently intense noise for a period of 

time. The U.S. Government’s Occupational Safety and Health 

Administration (OSHA) has specifi ed the permissible noise 

level exposures shown in the following chart.

According to OSHA, any exposure in excess of these permissible limits 

could result in some hearing loss. To ensure against potentially dangerous 

exposure to high sound pressure levels, it is recommended that all persons 

exposed to equipment capable of producing high sound pressure levels 

use hearing protectors while the equipment is in operation. Ear plugs or 

protectors in the ear canals or over the ears must be worn when operating 

the equipment in order to prevent permanent hearing loss if exposure is in 

excess of the limits set forth here.
