iv SAFETY PRECAUTIONS Be sure to observe all these safety precautions. ■ Please READ through this manual carefully. It will enable you to use the BHT-7000 and CU-7000 correctly.
v W ARNING Handling the battery cartridge • Never disassemble or heat the battery cartridge, nor put it into fire or water; doing so could cause battery-rupture or leakage of battery fluid, resulting in a fire or bodily injury.
vi W ARNING • Do not look into the laser beam source through the reading window or point the reading window towards the eyes. The laser beam emitted through the reading window is harmful to the eyes. • Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation expo- sure.
vii CAUTION Basic handling tips • Never put the BHT in places where there are excessively high temperatures, such as inside closed-up automobiles, or in places exposed to direct sunlight. Doing so could affect the housing or parts, resulting in a fire.
viii CAUTION • If you drop the BHT so as to damage its hous- ing, immediately turn off the power, pull out the dry batteries or the battery cartridge, and contact your nearest dealer.
ix CAUTION Handling the CU • If you will not be using the CU for a long time, be sure to unplug the AC adapter from the wall socket for safety. Failure to do so could result in a fire. • When caring for the CU, unplug the AC adapter from the wall socket for safety.
x ■ Proper Care of the BHT and CU Clean the housing and the battery cartridge terminals with a dry, soft cloth. Before cleaning, be sure to power off the BHT and unplug the AC adapter of the CU. • Never use benzene, alcohol, or other or- ganic solvents.
xi FCC Regulations This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.

135 Appendices ■ Abnormal termination of phase 1 (Abort of phase 1) If the sending station receives no ACK from the receiving station after sending an ENQ 10 times in succession, it sends an EOT to the receiving station after three seconds from the 10th ENQ to terminate the message transmission abnormally.
136 Phase 2: Data Transmission ■ Normal phase 2 The sending station first sends a transmission block containing the heading text. Each time the sending station receives an ACK from the receiving station, it sends a transmission block containing the data texts as shown below.
137 Appendices NAK NAK NAK NAK NAK ACK ■ Phase 2 with NAK If the sending station receives a NAK from the receiving station in response to a transmission block containing text data m, it sends that transmission block again immediately as shown below.
138 EOT 3 seconds 3 seconds ENQ ENQ ACK ■ Phase 2 with EOT If the sending station receives an EOT anytime during phase 2, it shifts to phase 3 to terminate the message transmission abnormally. Even if the phase 3 terminates normally, the transmission results in an abnormal end.

141 Appendices [ 2 ] Aborting Data T ransmission Pressing the C key aborts data transmission. If the C key is pressed during downloading, the BHT-7000 transmits an EOT and aborts the file transmission. If it is pressed during uploading, the BHT-7000 transmits the current transmission block followed by EOT and then aborts the file transmission.
142 S T X E T X B C C [ 3 ] BCC for Horizontal Parity Checking To check whether data has been transmitted accurately, the BHT-7000 supports hori- zontal parity checking for every transmission block. In horizontal parity checking, a horizontal parity byte so called BCC (Block Check Character) is suffixed to an ETX of every transmission block.
143 Appendices B.2 BHT -Ir pr otocol [ 1 ] T ransmission Control Sequences Shown below is a typical message transmission sequence supported by the BHT-Ir protocol.
144 Data transmission may accidentally involve various types of errors. The BHT-Ir proto- col is designed to recover from those errors as frequently as possible.
145 Appendices ■ Abnormal termination of phase 1 (Abort of phase 1) If the sending station receives no sequence of DLE ACK and IDs from the receiving station after sending a sequence of DLE ENQ and IDm 60 times in succession, it sends a sequence of DLE EOT and IDm to the receiving station after 0.
146 Phase 2: Data Transmission ■ Normal phase 2 The sending station first sends a transmission block containing the heading text. Each time the sending station receives a sequence of DLE ACK and IDs from the receiving station, it sends a transmission block containing the data texts as shown below.
147 Appendices ■ Phase 2 with suspension of data reception for erasure of the flash memory If the receiving BHT-7000 requires the flash memory to be erased for receiving downloaded files, it sends a sequence of WACK and IDs to the sending station to suspend the data transmission.
148 ■ Phase 2 with a sequence of DLE NAK and IDs If the sending station receives a sequence of DLE NAK and IDs from the receiving station in response to a transmission block containing text data m, it sends that transmission block again immediately as shown below.
149 Appendices ■ Phase 2 with a sequence of DLE EOT and IDs If the sending station receives a sequence of DLE EOT and IDs anytime during phase 2, it shifts to phase 3 to terminate the message transmission abnormally. Even if the phase 3 terminates normally, the transmission results in an abnormal end.
150 ■ Abnormal termination of phase 2 (Abort of phase 2) If the sending station receives no sequence of DLE ACK and IDs from the receiving station after sending a sequence of DLE ENQ and IDs 59 times in succession, it sends a sequence of DLE EOT and IDs to the receiving station after 0.
151 Appendices ■ Phase 3 with iterated transmission of DLE EOT and IDs due to no re- sponse or invalid response If the sending station receives no response or any invalid response from the receiving station in response to the sent sequence of DLE EOT and IDs, it iterates sending of the sequence at 0.
152 ■ Phase 3 with timeout at the receiving station If the receiving station receives no subsequent text or normal sequence of DLE EOT and IDs within 30 seconds after sending a sequence of DLE ACK and IDs, it sends a sequence of DLE EOT and IDs and aborts the transmission abnormally.
153 Appendices [ 3 ] CRC To check whether data has been transmitted accurately, the BHT-Ir protocol supports CRC (Cyclic Redundancy Check) which employs the CRC-16 generating system. In CRC, a CRC character is suffixed to a sequence of DLE ETX of every transmission block.
