Are these connection parameters okay?

Hi,

Are these connection parameters okay?

#define MIN_CONNECTION_INTERVAL    MSEC_TO_UNITS(7.5, UNIT_1_25_MS)
#define MAX_CONNECTION_INTERVAL    MSEC_TO_UNITS(15, UNIT_1_25_MS)
#define SLAVE_LATENCY              36 
#define SUPERVISION_TIMEOUT        MSEC_TO_UNITS(4000, UNIT_10_MS)

We have been seeing random disconnections with error 0x08(connection timeout) in the field. Is there any relation to those values?

These values are chosen my predecessor So I really don't know what was the reason for choosing those values. I'm not sure those parameter really help in optimizing the power. 

Please note that connection parameter are set by the central device(proprietory/nRF51).

You will get a connection timeout when the device is out or range - so what is the signal level when you see these ?
