This symbol, adjacent to a terminal, indicates that, under normal use, hazardous voltages may be present Double insulation SAFETY NOTES • Do not exceed the maximum allowable input range of any function. • Do not apply voltage to meter when resistance function is selected. • Set the function switch OFF when the meter is not in use. • Remove the battery if meter is to be stored for longer than 60 days. WARNINGS • Set function switch to the appropriate position before measuring. • When measuring volts do not switch to current/resistance modes. • Do not measure current on a circuit whose voltage exceeds 600V. • When changing ranges always disconnect the test leads from the circuit under test. • Bluetooth UL Note A UL mark does not indicate that this product has been evaluated for accuracy. CAUTIONS • Improper use of this meter can cause damage, shock, injury or death. Read and understand this user manual before operating the meter. • Always remove the test leads before replacing the battery or fuses. • Inspect the condition of the test leads and the meter itself for any damage before operating the meter. Repair or replace any damage before use. • Use great care when making measurements if the voltages are greater than 25VAC rms or 35VDC. These voltages are considered a shock hazard. • Always discharge capacitors and remove power from the device under test before performing Diode, Resistance or Continuity tests. • Voltage checks on electrical outlets can be difficult and misleading because of the uncertainty of connection to the recessed electrical contacts. Other means should be used to ensure that the terminals are not "live". • If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired.

Hopping Information 1. Hopping Range Hereby we declare that the maximum frequency of this device is: 2402-2480MHz. This is according the Bluetooth Core Specification V1.2 for devices which will be operated in the Europe. This was checked during the Bluetooth Qualification tests. Other frequency ranges (e.g. for USA, China, Japan) which are allowed according the Core Specification are not supported by this device. 2. Hopping Sequence Example of a 79 hopping sequence in data mode: 33,04,21,44,23,42,53,46,55,48,40,59,72,29,76,31,08,73, 07,75,09,45,60,39,58,13,47,11,77,52,35,50,65,54,67,56, 69,62,71,64, 37,25,27,66,57,70,74,61,78,63,10,41,05,43, 15,44,64,68,02,70,06,01,51,03,55,05,03,66,53,49,36,47. 3. Receiver input bandwidth The input bandwidth of the receiver is 1MHz. In every connection one Bluetooth device is the master and the other one is the slave. The master determines the hopping sequence. The slave follows this sequence. Both devices shift between RX and TX time slot according to the clock of the master. Additionally the type of connection is set up at the beginning of the connection. The master adapts its hopping frequency and its TX/RX timing according to the packet type of the connection. Also the slave of the connection will use these settings. Repeating of a packer has no influence on the hopping sequence. The hopping sequence generated by the master of the connection will be followed in any case. That means a repeated packet will not be send on the same frequency, it is send on the next frequency of the hopping sequence.
